Abstract

PURPOSE:To prevent a load from collapsing by inserting a cotton thread between plate-shaped workpieces when piled up together, so as to increase frictional resistance between the cotton thread and the plate-shaped workpiece. CONSTITUTION:A conveyed object 1 is formed by piling up many sheets of plate-shaped workpieces W of glass plate or the like. When the plate-shaped workpiece W is piled up, a cotton thread 2, while folded back, is continuously inserted between the plate-shaped workpieces W, W. The conveyed object 1 comprising many sheets of the plate-shaped workpieces W piled together while inserting the cotton thread 2, when conveyed, is loaded in a horizontal condition on a pallet 3 and conveyed by holding the pallet 3 to a conveying machine. In the method thus performed, by own weight of the plate-shaped workpiece W and a load by vertical oscillation at conveying time, the cotton thread 2 is closely attached to a sliding surface of the plate-shaped workpiece W to increase frictional resistance and to prevent load collapse at conveying time by eliminating slipping each plate-shaped workpiece W, and also the workpiece W can be prevented from being damaged by the load collapse.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing collapse of loads when stacking plate-like works such as glass plates and stainless plates having smooth surfaces and slippery, and conveying them in a horizontal state.

[0002]

2. Description of the Related Art In the case of stacking plate-like works having smooth surfaces such as glass plates and stainless steel plates and slippery in a horizontal state, that is, in a flat stack and carrying them by a conveyor, a crane, a fork truck, etc., start of a carrier machine, The stacked plate-like works are likely to collapse due to stoppage, vibration of the carrier, or the like.

Therefore, conventionally, as shown in FIG. 4, a conveyed article 1 in which plate-like works W such as glass are stacked and placed in a horizontal state.
01 The film 102 is wound around the whole end portion, fixed and placed on the pallet 100 for transportation, or the entire conveyed object 101 is tied with a string 103 as shown in FIG. There is.

[0004]

Of the above-mentioned conventional load collapse prevention methods, in the method of winding a film,
The film is stretched by a film winder to give elasticity while it is wrapped around the corners of the conveyed work, so the film is easily cut at the edge of the plate-like work, and the film is cut or peeled off to form a long strip. The film is wound around the roller of No. 3, the light of the photoelectric limit switch is blocked, and the malfunction is caused. Further, the film winding machine itself is expensive, and the film itself is expensive, so that the cost is increased as a whole.

Further, in the method of binding with a string or the like, if the tightening method is loose, the load tends to collapse, and if the tightening method is too tight, the plate-like work having a low edge strength is easily damaged, and an automatic machine has been developed. Since it is not done, it has to be done manually and the workability is poor.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a cotton thread is continuously or separately inserted between plate-like works when stacking the plate-like works.

[0007]

Since the cotton thread is inserted between the stacked plate-like works, the cotton thread and the plate-like works have a frictional resistance to prevent the load from collapsing.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a conveyed product which has been subjected to the load collapse prevention method according to the present invention, FIG. 2 is an enlarged sectional view of FIG. 1, and FIG. 3 is an enlarged sectional view of another embodiment.

A large number of conveyed articles 1, for example, 100 to 20
It is made by stacking plate-like works W such as 0 glass plates.
When the plate-like works W are stacked, the cotton yarn 2 which is commonly referred to as a cut yarn is folded back and continuously inserted between the plate-like works W.

Here, the insertion depth D of the cotton thread 2 between the plate-shaped works W may be set arbitrarily, and the number of the cotton thread 2 to be inserted is not limited to one, but may be plural. Further, not only the insertion from one direction but also the insertion from two directions, three directions and four directions may be performed.

Then, when the article 1 made up of a large number of plate-like works W stacked while inserting the cotton thread 2 in this way is conveyed, it is placed horizontally on the pallet 3 and the pallet 3 is conveyed. Hold the machine and transport.

At this time, since the cotton thread 2 is inserted between the respective plate-like works W, the cotton thread 2 receives the load due to the weight of the plate-like work W and the vertical vibration at the time of conveyance, so that the cotton thread 2 becomes the plate-like work W.
Friction resistance occurs due to the close contact with the smooth surface of each plate work W, making it difficult for each plate work W to slip and preventing collapse of the load during transportation. Therefore, the work W itself is not damaged due to the load collapse prevention measure for the plate-shaped work W.

Next, in another embodiment of FIG. 3, when the plate-like works W are stacked, the cotton threads 2, 2 are provided between the plate-like works W.
Are individually inserted, and in this case, the workability of inserting the cotton thread 2 is advantageous in that the work of folding back the cotton thread 2 is unnecessary as compared with the case of the above embodiment. is there.

The plate-like work to which the present invention is applied is not limited to a glass plate, a stainless plate or the like whose surface is a sliding surface itself, and a slippery cushioning material such as powder is interposed on the surface. However, in this case, a cotton thread thicker than this gap may be inserted into the air layer, that is, the gap between the plate surfaces of several tens of microns.

[0015]

As described above, according to the present invention,
Since the cotton threads are inserted between the plate-like workpieces when stacking the plate-like workpieces, the frictional resistance between the cotton thread and the plate-like workpieces can prevent the cargo from collapsing during transportation, and it is easy and easy. Since the edge portion of the sheet does not become damaged and the quality is not deteriorated, and the cotton thread itself is inexpensive, the cost does not increase, and it is possible to reliably prevent the collapse of the load during the transportation of the plate-shaped work.
