Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel conveyor chain of the type in which attachments are mounted separately from the chain links.

For conveyor chains with attachments, as is well known, the part of the link plate that corresponds to the attachment is bent outward at 90 degrees from the link part using a single plate, or a separately manufactured part is welded to the outside of the link plate. Since these are assembled and connected using bushings and pins, the degree of accuracy of machining and assembly of each part greatly affects the flatness of the top surface of the attachment. When a slat is attached to the top surface of this attachment and used as a conveyor with a flat surface, the top surface of the slat is difficult to exhibit a uniform flat surface, and therefore the conveyed object may move due to vibration, or it may be difficult to support and convey long objects. There are problems such as a lack of accurate support when carrying out the work.

However, conventional attachments, especially those that bend a protrusion formed on a part of the link plate, cannot solve the above-mentioned problems due to the nature of the cheno and cannot be used like other mechanical elements. It was said that it was virtually difficult to finish it with high precision.

The present invention solves these conventional problems and improves the conveyor installation section so that the conveyance surface of the conveyor is always flat and stable, and there is no vibration or unevenness of the support surface, depending on the conditions and circumstances of use. Equipped with functions that can respond to various conditions,
Furthermore, the object of the present invention is to provide a conveyor chain with an attachment that can be easily mass-produced and provided at low cost.

Furthermore, the present invention provides a conveyor chain in which the attachment portion can be attached to and detached from the link plate as necessary, and attachments with different dimensions or other types of attachments can be easily attached in some cases. There is a particular thing.

In order to achieve such an object, the present invention provides one or more pins protruding laterally from the intermediate side surface of a link plate to which an attachment is attached, and a separately formed link side mounting portion of the attachment is provided with a pin that is covered with the pin. If there is no attachment hole provided, the attachment hole can be fitted into the attachment pin of the link plate, and it can be moved in a direction almost perpendicular to the line connecting the centers of the connecting pins of the link plate. A conveyor chain with an attachment is constructed by attaching the conveyor member to the upper surface of the attachment so that the lower surface protruding from the attachment is slidably supported by a guide rail.

Furthermore, in the present invention, although the attachment and its mounting are made to stably hold the connection between the link plate and the = in a freely movable state, the attachment on the link plate side is performed by attaching a locking means to the pin, so that the connection between the link plate and the = can be stably maintained after the attachment is mounted. This prevents the device from coming off while it is in a removable state.

Furthermore, according to the present invention, a pin is fixed to the side surface of the link plate, and a separately formed attachment for this is not required in the required size and shape, and the attachment of such an attachment is done so that the part matches the pin on the link plate side. For installation, a hole is provided, and the hole is removably attached to the chain link, making mass production of standard chain links easier. By doing so, it becomes possible to meet various demands, and a conveyor chain that can be easily mass-produced and provided at a low price can be obtained.

Below, one embodiment of the conveyor chain of the present invention will be described in detail with reference to concrete example diagrams. The conveyor chain shown in FIGS. 1 to 3 is of a type in which an attachment is freely attached to the chain body, is a conveyor chain of a well-known structure, in which a link plate 2 is connected by a bush 3 and a connecting pin 4, and a roller 5 is fitted onto the bush 3. Two pins 6 are attached at a required pitch P at right angles outward, respectively, by fixing pins 6 at their base ends and protruding a suitable length.

On the other hand, the attachment 10 is formed into an angle shape, and when the link plate 2 is installed in an upright position, the inner diameter of the link plate 2 is set to the outer diameter of the pin 6 at intervals that match the pitch P of the pins 6. For installation slightly larger than hole 1
2 is provided, and the hole 12 is formed by fitting a bush 13 with suitably increased strength, and the horizontal upper part 14 is provided with/or a plurality of screw holes 15 for mounting the conveyor plate 20 at required positions. The link plate 2 is attached to the pin 6 by fitting it into the hole 12 so that the attachment 20 thus made is positioned symmetrically on both sides of the chino 1.

Then, on the upper surface of the attachment 10.10, a conveyor plate 20 is fastened with bolts 17 using the mounting screw holes 15 in the horizontal upper part 14, and both the left and right attachments 10, 10 and the chino 1 are integrally connected via the conveyor plate 20. connected to.

In the conveyor chain of the present invention thus constructed, the lower surfaces of both sides of the conveyor plate 20 are slidably supported on the guide rails 25, as shown in FIG. 20 moves along the guide rail 25° 25 together with the chino 1, and is fastened to the conveyor plate 20 to form an integral actuator (10, 10).
Both link plates 2 of the chino 1 are horizontally mounted with pin 6, and mounted integrally by engagement with hole 12, and this mounting is done because hole 12 has a slightly larger diameter than pin 6. Attachment 10.10 is attached to the chain due to the dimensional difference between the outer diameter of pin 6 and the inner diameter of hole 12 when attaching the link plate, and between the side of link plate 2 and the side of attachment 10 when attached to the link plate. Due to the gap, the conveyor plate 20 runs along the guide rail 25 surface, and each attachment 10 runs in a direction almost perpendicular to the line (7) connecting the centers of the connecting pins of the chino (see Figure 2). (It is not limited to right angles) and can be operated in a stable state without being directly affected by errors in the precision of the cheno.

In other words, although the chain 1 and the conveyor plate 20 do not come off and are securely attached, the pin connection to the link plate of the attachment prevents problems during operation due to machining accuracy on the chain side. Since it is now possible to operate without affecting the conveyor placed on the conveyor plate 20 by blocking the conveyor, it can be used, for example, in woodworking machines that carry out processing by placing long objects on the conveyor. It can completely prevent the influence of the chain side from occurring on the processing surface, or it can be used in the container transport section of food processing machines to prevent collision noise caused by vibration when containers are transported between each other (reducing noise). Easily solves a wide range of problems that occur with conventional conveyors, such as making it possible to reliably prevent overflow from the mouth due to vibration of the contents (liquid) in the container before sealing. It is possible.

In the specific example described above, the attachment 10 is of a type that simply fits onto the mounting pin 6 of the link plate 2, and both of them have a member for supporting the conveyed object, such as the conveyance plate 20, as illustrated. Since it is integrated with the ceno via the link, the link and the attachment can be easily separated until the conveyance plate 20 and the like are attached.

Therefore, as shown in FIGS. 4 and 5, the link plate 2
A groove 7 is formed in the tip of each mounting pin 7.
A spring clip 8 with an elongated hole 8' extending between both mounting pins 7 and 7 is inserted into the groove 7 at the tip of the mounting pin.
The spring clip 8 prevents the attachment 10 from coming off easily.

With this configuration, when supplying the ceno to a consumer, it can be supplied with the attachments 10 attached to each link chain, which is convenient for the consumer to attach members to the attachments according to the object to be transported. This has the advantage that there is no risk of losing parts.

Even with this configuration, the function similar to that of the specific example described above is exhibited without any problem, and when replacing the attachment or replacing only the chino, the spring clip 8 can be attached to the pin 7. The purpose can be easily achieved by removing it from the groove 7'.

In addition, as a means of locking an attachment in place of the spring clip described above, when mounting on the link plate side, a small hole is bored at the tip of the pin perpendicular to its axis, and when mounting multiple pins, each Or, a method in which a series of well-known split pins are used to pass through a series of pins, and the split pins are used to prevent the attachment from coming off.

Alternatively, a method can be adopted in which an attachment is attached by inserting a wire bent in an S-shape into a small hole drilled at the tip.

Next, based on the technical idea of the present invention, the configuration of the cheno can be left as is, and even if the attachment is of the angle type described above, it can be installed by standardizing only the dimensions of the parts and replacing it with one of different dimensions. Can be used for various sizes.

Alternatively, it has the advantage that attachments of different shapes can be attached and used for various types of chino-driven conveyors.

Further, according to the present invention, the shape of the pin for attachment may be oval, square, or polygonal in addition to the circular pin as in the above specific example, and the shape can be selected depending on the application. Of course, for mounting the attachment, the number of mounting pins may be one or two or more.

Further, according to the spirit of the present invention, it is also possible to use a synthetic resin material with high mechanical strength for the attachment of a ceno, and to use it in a relatively light-load conveyor or the like.
