Description

[Detailed description of the invention] The present invention is an automatic glass plate collecting machine for transporting and feeding interleaving paper between glass plates while removing static electricity, and for supporting the glass plates in a vertical position. Specifically, a pair of conveyor belts for conveying and supplying interleaving sheets between a glass plate that is placed and supported in a vertical position and a glass plate that is transferred from a transfer device to a vertical position by a transfer device. The present invention relates to an automatic glass plate collecting machine, which includes a conductor that dissipates static electricity charged on the interleaving paper during conveyance by bringing it into contact with the interleaving paper.

According to the above-mentioned automatic glass plate collecting machine, the interleaving paper after static electricity has been removed can be sandwiched between the glass plates, and thereby the interleaving paper, especially its lower end, is laminated. This automatic glass plate collecting machine completely avoids adsorption to the glass plate due to Coulomb force and can feed interleaf paper smoothly and in good condition without wrinkles. Conventionally, a conductor was provided independently on the lower side of the transport of interleaving paper by a pair of conveyor belts, and the interleaf paper sent out from the pair of conveyor belts was supplied between the glass plates while contacting the conductor. By timing-driving the pair of conveyor belts based on the detection results from the detector that detects the movement of the glass plate being transferred from the device side, the interleaving paper can be transferred to the glass plate whose lower end is placed in a vertical position. The glass plate is configured to be switched between a state where the glass plate is held in an upward position near the lower end position and a state where the glass plate is dropped and supplied just before the glass plate is transferred in a vertical position by the transfer device,
If you want to feed interleaving paper efficiently and quickly, and to hold the lower end of the interleaving paper in a position above the bottom edge of the glass plate, the upper end of the interleaving paper must be held between a pair of conveyor belts. There is a problem that the removal of static electricity by the conductor becomes incomplete, and it becomes difficult to insert the interleaf paper between the glass plates in the specified position and orientation.Furthermore, depending on the type of glass plate, the thickness In this case, it is necessary to adjust the clamping force of the pair of conveyor belts depending on the thickness of the sheets, and the relative position of the pair of conveyor belts must be changed to adjust the clamping force. etc,
Another problem was that the adjustment operation was time-consuming.

In other words, when switching from a state in which the upper end of the interleaf paper is held in that position by a pair of conveyor belts to a state in which the pair of conveyor belts is activated and the sheet is fed falling, Static electricity is generated with the operation of the pair of conveyor belts, but the static electricity generated at this time is removed by the contact between the interleaving paper, which is in an unstable position, and the conductor during free fall. As a result, the removal of static electricity will be incomplete, and the interleaf paper will fall freely while contacting the conductor, which will disturb the posture of the interleaf paper and prevent it from being sandwiched between the glass plates at a predetermined position and attitude. This is because the interleaving paper cannot be inserted, and the interleaf paper may be inserted in a crooked, overlapping state, or in an inclined position.

The present invention aims to solve the above-mentioned problems by devising the mounting position of the conductor.

The characteristic configuration of the present invention for achieving the above object is that, in the above-mentioned automatic glass sheet picker, one of the pair of conveyor belts is connected so that its terminal end is closer to the end of the other conveyor belt. The conductor is also disposed so as to be located on the downstream side in the interleaving paper conveyance direction, and the conductor is disposed in contact with the extended portion of the one of the conveyor belts, and further, the conductor is A detector for detecting movement of a glass plate transferred from the transfer device, comprising a pressure spring for pressure contact with paper and an elastic force adjuster for adjusting the elastic force of the pressure spring. By timing-driving the pair of conveyor belts based on the detection results from the pair of conveyor belts, the upper end side of the interleaf sheet is held between the one conveyor belt and the conductor;
and a state in which the lower end side of the glass plate is placed and supported in a vertical position and is held in a vertical position located above the lower end position of the glass plate, and a glass plate is transferred in a vertical position by the transfer device. The structure is such that the state is switched to the drop supply state just before the drop, and the following effects are obtained from this structure.

That is, the terminal end of one of the pair of conveyor belts is extended so as to be located on the lower side in the paper conveying direction than the terminal end of the other conveyor belt, and this extended portion and the Since the upper end side of the interleaf paper is held in a vertical position by being held between a conductor equipped with a spring, the above-mentioned problems of the conventional automatic glass plate collecting machine can be solved.

In other words, the state in which the interleaf paper is held at that position with its upper end held between one of the conveyor belts and the conductor is changed to the state in which it is fed falling as one of the conveyor belts operates. The static electricity that sometimes occurs is immediately removed by the conductive material that holds one side of the interleaving paper.

In addition, unlike conventional methods, there is no contact with a separate, independent conductor during the falling supply, so there is less disturbance in the posture of the interleaving paper during free fall.
The interleaving paper is held in a vertical position by a combination of a configuration that clamps and holds the interleaving paper, and a configuration that switches to a state where the glass plate is dropped and fed just before the glass plate is transferred in the vertical position by the transfer device. It is easy to reliably feed between the glass plates at a predetermined position and orientation.

Furthermore, in addition to the configuration in which the interleaf paper is held between one of the conveyor belts and the conductor, an elastic force adjustment tool is provided to adjust the elastic force of the pressure spring for press-contacting the conductor to the interleaf paper. Even if the thickness of the interleaving paper changes, it is now possible to adjust the clamping force extremely easily by simply operating this elastic force adjuster without having to change the relative position of the pair of conveyor belts. .

In addition, as mentioned above, since the interleaf paper is held in a vertical position and fed by falling, it is extremely effective for use with ordinary glass plate automatic plate collecting machines that place heavy glass plates in an upright position. It is possible.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, among a pair of conveyor belts 4 and 5 constituting the feeder 3, the lower end of the drive belt 4, which is one conveyor belt, is lower than the lower end of the driven belt 5, which is the other conveyor belt. In other words, a conductor 13, which is a feature of the present invention, is provided so as to extend toward the lower side in the interleaving paper conveyance direction, and correspond to the extended portion of the drive belt 4.

The conductor 13 is provided as a thin pinch plate that pinches the waiting paper 1 between the conductor 13 and the lower end of the drive belt 4. This conductor 13 is screwed to a holder 15 that is pivotally supported on the frame via a shaft 14, and a spring 16 for press-welding the interleaving paper and its elastic force adjusting device (screw) 17 are attached to the holder 15. There is. A weight may be used instead of the spring 16. The conductor 13 is then grounded through a feeder or the like.

Feeding roll 2, drive belt 4, driven belt 5
A plurality of sets are arranged side by side, and each set is equipped with a conductor 13 and an attached member. Therefore, the pressing force of each conductor against the rectangular interleaving paper 1 can be adjusted according to the condition of each set of belts without being influenced by the condition of other belts. In other words,
Conventionally, due to the structure in which the five groups of driven belts are adjusted all at once, it has been extremely difficult to equalize the pressure contact force of all feeders, which has been improved.

Next, the operation of the automatic glass plate sampling machine according to the present invention will be explained as follows.

(a) The feeding roll 2 delivers the rectangular interleaving sheets 1 one by one to the feeding feeder 3. The feeder 3 consists of a drive belt 4 and a driven belt 5, which are a pair of conveyor belts in a vertical position, and feeds the interleaving paper 1 until its lower end reaches a position with a slight fall distance h from the support surface of the conveyor table 6, and then waits. do.

(b) The glass plate G is supplied in the direction of the arrow by a conveyor 7, which is an example of a transfer device, and is automatically loaded onto the conveyor table 6 by a suction cup type transfer device 8. 9
1 is a detector for detecting the passage of the glass plate G, and 10 is a cylinder. The detector 9 is connected to the cylinder 10, roll 2, feeder 3, etc. via a control device.

(C) Just before the glass plate G is transferred, the feeder 3 (at the position of the imaginary line) is driven at a timing to release the waiting interleaf paper 1 and feed it between the glass plates.

According to the above embodiment, the amount of downward protrusion of the driven belt 5 located on the side of the transfer device 8 is small, and the thin conductor 13 and the drive belt extend downward from the lower end of the driven belt 5. Since the upper end side of the waiting slip sheet 1 is held between the lower end of the slip sheet 1 and the lower end of the slip sheet 1, the static electricity generated when switching from the state where the slip sheet 1 is held to the state where the slip sheet 1 is dropped and fed is absorbed by the one side of the slip sheet 1. In addition to having the effect of being immediately removed by the conductor 13 in contact with the surface, the lower end of the drive belt 4 of the feeder 3 is positioned further down with respect to the movement trajectory 12 of the transferred glass plate G. As a result, the falling distance h is also reduced, and the interleaving paper 1 is less disturbed by the impact of the fall.

In the present invention, instead of providing the conductor 13 on the driven belt 5 side, the conductor 13 is provided on the drive belt 4 side so as to correspond to the lower end of the driven belt 5 and extend downward from the lower end of the drive belt 4. Good too. However, in this case, in order to prevent the lower end of the driven belt 5 from entering the movement locus 12, it must be placed high as in the conventional case, and therefore the fall distance h does not decrease.

The conductor may also be a pinch roller instead of a pinch plate, and it is well known that the pinch plate can sufficiently remove static electricity from the paper 1 as long as it is in contact with only one side of the paper 1. A pair of pinch plates, pinch rollers, or contact brushes may be used for both the front and back sides of the paper 1.
