Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a device for conveying linen one by one in a laundry factory, one piece of cloth such as a hand towel, gauze, diaper, etc.
The present invention relates to a linen transfer conveyor that can be used in a device for transferring sheets.

(Prior Art) Conventionally, there are various kinds of conveyors that convey linen (sheets, towels, yukata, etc.) one by one in a laundry factory or the like. 1
As an example, the operator develops the sheets after washing and dehydration,
As a spreader feeder for a labor-saving machine before being put into a roll ironer, a hanging-type conveyor is known in which an operator grips two adjacent ends of a sheet by a moving chuck and conveys the sheet.

This conventional conveyor will be described with reference to FIGS. 4 to 7, and 1 is a sheet, which is shown as a representative of linen. After the sheets 1 are washed and dehydrated, they are unraveled and unfolded by an operator.
The two adjacent ends are gripped and conveyed by the chuck 2. The chuck 2 has a torsion spring 23 inside, and the sheet 1 is sandwiched and held by the housing 21 and the lever 22. Further, as shown in FIG. 6, the lever 22 is always urged counterclockwise about the pin 24 in the housing 21. Also housing
A bearing 20 is provided on the head of 21 so that it can move freely inside the supply rail 11. 25 is a weight for balance adjustment.

Reference numeral 10 is a spreader feeder, and the sheet 1 can be expanded by expanding the chuck 2 sandwiching the two ends of the sheet 1 sent from the rail 11 to the left and right. By opening
This is an automatic sheet spreading and conveying device that transports only the sheet 1 to the roll ironer 3 by a belt conveyor. After separating the sheet 1, the chuck 2 is automatically collected in the apparatus and discharged to the collecting rail 12 (FIG. 4).

The rail 11 conveys the chuck 2 sandwiching the sheet 1 to the spreader feeder 10. If the rail 11 is tilted in the power forward direction, the chuck 2 moves by its own weight. When the rail 11 is installed in a direction against gravity or in a horizontal direction, the chain 2 is moved by being pushed by the bracket 15 attached to the chain 16 circulating in the drive rail 13 (Fig. 5). . The recovery rail 12 is a rail that conveys the empty chain 2 separated from the sheets 1, and has the same structure as the rail 11. The drive rails 13 and 14 incorporate resin guides 17 therein, and the chains 16 circulate therein. The resin brackets 15 are attached to the chain 16 at a constant pitch, and the chucks 2 in the rail 11 and the recovery rail 12 are pushed and moved. Chain 16 is a sprocket
It circulates using 18 mag. Furthermore, the circulation chain 16
There is a gap between the roller and the pin so that it can be bent vertically and horizontally.

(Problems to be Solved by the Invention) In the above-mentioned conventional conveyor, as shown in FIG. 5, there are three supply rails 11 and drive rails (transport side) 13 and drive rails (return side) 14 of chuck 2. Books are basically needed. The drive system chain 16 and bracket 15 are exposed to the outside of the rails, so that the linen may be soiled or damaged if it is transported on a steep slope or if the layout makes contact with the rails. It is expected that Further, there is a high possibility that foreign matter may be caught in the chain and cause a failure. Further, there is a problem in that the position and height of the rail through which the chain passes and the rail of the drive system and the bracket need to be adjusted at the time of installation and construction.

The present invention is proposed to solve the above conventional problems.

(Means for Solving Problems) Therefore, in the present invention, in a device for transporting linen using a rail, the rail is formed in a U-shaped cross section, and is divided into an upper space and a lower space. The drive system chain is movably installed in the guide installed in the space, and pins are connected to the lower part of the chain at a constant pitch, and the rollers integrated with the chuck are stored in the lower space so that the pins can run. Then, the chuck is conveyed through the roller, and this is used as a means for solving the problem.

(Operation) The drive system chain is mounted in a guide installed in the upper space of a rail with a U-shaped cross section so that it can travel, and the pins connected to the chain form a roller integrated with the chuck housed in the lower space of the rail. Since it is transported, the rail does not come into contact with it and the linen is not contaminated or damaged. Further, since the drive system chain and the rail are integrated, it is possible to greatly reduce the labor such as height tensioning during installation work.

(Embodiment) The present invention will be described below with reference to the embodiments of the drawings. Figs. 1 to 3 show an embodiment of the present invention. First, Fig. 1 and 2
Referring to the first embodiment of the drawing, this first embodiment shows an example of a chuck 114 and a conveyor 115. FIG. 1 shows a front view and FIG. 2 shows a side view thereof in a sectional view. It is a thing. In the figure, the chuck 114 has a spring 135.
The sheets 134 are levers 133, 13 by pressing down the pin 134 fixed to the frame 143 constantly by the spring force of
It has a structure that holds it at 3. Then, when the levers 133, 133 are pushed up by an external force in the direction of the arrow in the figure, the lever 133
Is rotated about the pin 134 as shown by a chain double-dashed line to release the holding of the sheet 1. Further, the chuck 114 is a roller 136 rotatably supported by the frame 143.
Moves along the lower rail 139 of the transportation side rail 139, and its driving force is transmitted by pins 142 fixed to the lower portion of the chuck 138 at a constant pitch as shown in the figure.

Further, 140 is a guide, the lower part of which is supported by a protrusion 139a protruding inside the transportation side rail 139, and a chain 138 is mounted in the inner hole portion so as to be able to travel. The guide is inserted in the length direction of the rail 139, and a predetermined portion is attached to the rail 139 with a pin (not shown). 141 is the return rail,
Like the transport side rail 139, it has a protrusion 141a, and the guide 1
I wear 40 in the same way. A rail cover 144 is attached to the lower opening of the return-side rail 141 to prevent foreign matter from entering the rail 141 and grease or dust from falling inside.

Next, the operation of the first embodiment of FIGS. 1 and 2 configured as described above will be described. When the chain 138 is driven via a pulley or the like (not shown), the pin 142 causes the frame 1 to move.
By pushing 43, the chuck 114 travels along the guide 140 of the transport-side rail 139. On the other hand, the return chain 138 runs along the guide 140 of the return rail 141. Further, the guide 140 may have a divided structure as shown by a chain double-dashed line in FIG.

Next, the second embodiment of FIG. 3 will be described. In this embodiment, the guides 240 and 240 are fixed to the rails 239 and 241 from which the projections 139a and 141a of FIG. 1 are removed by bolts or the like not shown. There is no difference in action and effect from the examples.

Here, in FIG. 1 and FIG. 3, if the distance between the rails 139 and 141 (or 239 and 241) is widened and the cover 144 is removed so that the chains 114 can pass each other, the return rail 1
41 and 241 can also be used as reverse transportation rails. In this way, the drive rail is not wasted, and there are great advantages in terms of space saving and cost.

(Effect of the Invention) As described in detail above, according to the present invention, the chain of the drive system is incorporated into the guide installed in the upper space of the rail having a U-shaped cross section so that the chain can travel, and the pin connected to the chain is used.
Since the roller integrated with the chuck housed in the lower space of the rail is conveyed, the rail does not come into contact with the linen to stain or damage the linen. Further, since the drive system chain and the rail are integrated, it is possible to greatly reduce the labor such as height adjustment during installation work.
