Description

[Detailed Description of the Invention] This invention relates to a steel wire bar conveyor used for transporting relatively lightweight items such as food.

Conventionally, as this type of conveyor, a straight conveyor or a curved conveyor is known, in which steel wire bars are stretched between two endless drive chains at predetermined intervals, and the conveyor can run freely along a guide rail. And the above conveyor is
It is very convenient when used alone in straight or curved sections, but in the case of complicatedly curved routes, straight conveyors,
It was necessary to use a suitable combination of conveyors and curve conveyors, and it was necessary to install a crossing device at the connection part. Therefore, a motor for driving each conveyor must be installed for each conveyor, which not only complicates electrical work and maintenance but also requires a large amount of power consumption. Furthermore, in food factories, etc., it is necessary to wash the conveyors frequently to keep them clean, so the washing machine must be moved and cleaned for each conveyor.
The cleaning work was very troublesome and required time and effort.

This invention attempts to solve the problems of the conventional products mentioned above all at once.It is possible to travel in a curved manner, and even on a complicatedly curved travel route, there is no need for a crossing device, and even a single conveyor can be used. Not only can the objects to be transported be transported smoothly, and the conveyor can be easily cleaned and maintained, but the return travel distance of the conveyor can be shortened, while the outbound travel distance can be increased. The purpose of this project is to provide a conveyor with extremely high conveyance efficiency.

An embodiment of this invention shown in the drawings will be described below.

Reference numeral 1 denotes a frame having an elongated rectangular cross section, 2 covers having a substantially U-shaped cross section provided opposite to each other on both sides of the frame 1, and 3 a cover disposed in parallel in the center of the frame 1 via a fixture. A pair of left and right drive chain guide rails 4 are provided, a pair of left and right steel wire bar guide rails located on both sides of the drive chain guide rail 3 and arranged upwardly at approximately the same height; It is an endless curved chain having flexibility in the lateral direction and spans between sprocket wheels 6, one of which is used for driving, and each outer link plate 7 of the curved chain 5 has a horizontal guide piece at its lower end. 8, each of the inner link plates 9 is provided with a horizontal guide piece 10 at its upper end, and the guide pieces 8, 10 of the inner and outer link plates 7, 9 also have the guide pieces 10 as shown in FIG. Holding rail 3, curved chain 5
can run freely along the guide rail 3. Reference numeral 11 denotes a substantially U-shaped steel wire bar that is attached to opposite sides of the curved chain 5 at a predetermined interval, and the steel wire bar 11 is formed by folding a slightly elastic steel wire in half. One end of the steel wire bar 11 is attached to one of the adjacent inner link plates 9, and the other end is attached to the other side of the backing plate 1.
2 and the mounting fittings 13 (see FIGS. 1 and 3). The steel wire bar 11 is brought into contact with the steel wire bar guide rail 4, and can freely run by sliding on the guide rail 4 as the curved chain 5 runs. 1
4 indicates a washing machine installed at a predetermined location on the conveyor route.

Next, the operation of the steel wire bar conveyor according to this invention will be explained.

For example, as shown in FIG. 4, when the drive sprocket wheel 6 is first driven on a substantially W-shaped travel route, the curved chain 5
slides on the guide rail 3, and the steel wire bar 11 slides on the guide rail 4, and starts running in the direction of the arrow. Since the curved chain 5 travels without bending on the straight travel path, the width between adjacent steel wire bars 11 is maintained uniform. When the curved chain 5 further travels and approaches a curved travel route,
Since the guide pieces 8 and 10 firmly and slidably hold the guide rail 3, the curved chain 5
gradually bends along the guide rail 3 and curves reliably. Then, in conjunction with the bending of the curved chain 5, the width between adjacent steel wire bars 11 expands and contracts. That is, as shown in FIG. 1, since the inner and outer link plates 7 and 9 located on the curved running surface each bend inward of the curved running surface, each of the inner and outer link plates 7 and 9 located on the outside of the curved running surface is interlocked with this. Both ends of the steel wire bars 11 are pushed outward to maintain an appropriate width between adjacent steel wire bars 11, while both ends of each steel wire bar 11 located inside the curved running surface are pushed apart. The width between adjacent steel wire bars 11 is reduced by being pushed inward. Similarly, the curved chain 5 travels along straight and curved travel paths, and when it reaches the sprocket wheel 6 at the other end, it rotates and starts traveling on the return side, and the guide rail 3 for the drive chain on the return side and the steel wire bar It slides on the guide rail 4, and after being cleaned by a washer 13 at predetermined intervals, it reaches the outbound running surface again. Thereafter, it circulates between the sprocket wheels 6 at both ends in the same manner.

In addition, in the above embodiment, the shape of the steel wire bar 11 is not only approximately U-shaped but also a corrugated steel wire folded in two as shown in FIG. Can be adopted. Further, the steel wire bar 11 has one end attached to one of the adjacent inner link plates 9 and the other end attached to the other side through the mounting brackets 13, and one end is attached to the adjacent outer link plate 9. One end of the plate 7 may be attached to the other end.

Since this idea is structured as described above,
In addition to running in a straight line, it is also capable of bending to the left and right, allowing objects to be transported continuously and smoothly even on complexly curved travel routes without the need for crossing devices. Since Chain 5 has only one thread, it is only necessary to install one motor, which not only allows operation with less power consumption compared to conventional products, but also allows for easy maintenance and inspection, making it easy to install a conveyor. Electrical work can be done easily. Furthermore, when cleaning the conveyor, it is only necessary to install a cleaning machine at one location, and cleaning can be carried out efficiently. Furthermore, since the conveyor according to this invention can freely travel in a bending manner, the running surface on the return side can be shortened and the running surface on the outgoing side can be lengthened, and the conveyance efficiency can be greatly improved. Furthermore, since guide pieces 8 and 10 that slidably sandwich the guide rail 3 are attached to each of the inner and outer link plates 7 and 9 that constitute the endless curved chain 5,
In particular, at bending points, the guide pieces 8 and 10 firmly hold the guide rail 3, so that the endless curved chain 5 can be reliably moved through the bend.
Moreover, since the mounting fittings 13 of the steel wire bars 11 and 15 are installed between the corresponding link plates on both sides, the top of the endless curved chain 5 can be almost completely closed off.
There is almost no contact between the conveyed object and the endless curved chain 5, and it is possible to effectively prevent the conveyed object from being soiled.
