Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an endless conveyor structure used for conveying articles such as food in containers, and is mainly used in the manufacturing process of the articles.

[0002]

[Prior Art]

 A plurality of endless chains are arranged in parallel, and a plurality of frame members extending in the width direction are laid between the chains in a line in the direction in which the endless body is driven. An endless conveyor having holes for fitting and supporting is disclosed, for example, in Japanese Utility Model Publication No. 59-24642.

The frame material of this endless conveyor is in the form of an integral plate having a hole for supporting the product, and the product is supported by the edge of the hole and conveyed.

[0004]

[Problems to be solved by the device]

 However, since the frame material is wholly integral and the holes are directly formed in the frame material, it is possible to use the endless conveyor when carrying an article of another shape or size. Can not. For example, if this endless conveyor is used in a production line for food products in containers, the entire endless conveyor is replaced or the frame material itself is replaced when manufacturing products with different container shapes or sizes on the production line. There was a need.

In this case, it takes a lot of time and money to replace the entire endless conveyor, and when the frame material is replaced, a large number of bolts and nuts are used for the endless chain. Since it has to be replaced by attaching and detaching, etc., it is troublesome, and there is a problem that the cost increases even if it is not enough to replace the entire conveyor. Therefore, the present invention provides an endless conveyor capable of easily and inexpensively transporting another item even if the size or shape of the item to be transported is changed by simply exchanging a part of the frame material. Has a purpose.

[0006]

[Means for Solving the Problems]

 In the endless conveyor structure of the present invention, a plurality of endless chains to be driven such as an endless chain are arranged in parallel, and a plurality of frame members extending in the width direction are arranged between the endless bodies in the direction in which the endless body is driven. In an endless conveyor in which the frame material is provided with holes for supporting articles to be conveyed, the frame material supports the outer frame installed between both endless bodies and the article. The outer frame is formed with a hole and is configured to be detachably attached to the outer frame.

[0007]

[Action]

 When an object of a certain shape and size is to be transferred from another object of a different shape or size due to changes in the object to be transferred, remove the supporting piece used up to that point from the outer frame and add a new product. A new support piece with holes corresponding to the shape and size is attached to the outer frame. Thus, by making the support pieces compatible, the same conveyor can be used to convey items of different shapes or sizes.

[0008]

【Example】

 1 to 3 are embodiments showing a part of an endless conveyor structure according to the present invention. In this embodiment, the endless conveyor is a conveyor used in a food production line for containers. Thus, the conveyor carries the food product or a container prior to the food product.

That is, the outer frame 1 is integrally formed of, for example, an aluminum alloy and has a plurality of rectangular through holes 2 formed in the longitudinal direction. This longitudinal direction corresponds to the width direction of the endless conveyor. A frame member 4 is constructed by detachably mounting a support piece 3 on the outer frame 1. The support piece 3 is mounted corresponding to each through hole 2. The supporting piece 3 is formed by forming a hole 6 in a plate member 5 having a size and shape that closes the through hole 2 to support an item by engaging an edge thereof, and the periphery of the hole 6 is integrally raised from the plate member 5. Edges are formed by the circular ridges 7, and on the outer surfaces of the ridges 7 opposite to each other, two flat width portions 7a are formed in total at two locations.

A guide 8 for the inner surface of the through hole 2 of the outer frame 1 is provided on the lower surface of the plate member 5, and a tongue piece 9 that passes through the through hole 2 of the outer frame 1 and reaches the back surface is also provided on the lower surface of the plate material 5. At the lower end of the tongue piece 9, a claw 9a that engages with the back surface of the outer frame 1 is formed. The tongue piece 9 has a slight elasticity and can be bent toward the inside of the through hole 2, thereby allowing the claw 9a to be detached from the back surface of the outer frame 1. Two tongue pieces 9 are formed on the opposite sides of the hole 6 through the center of the hole 6. The guide 8 is in contact with the periphery of the through hole 2 of the outer frame 1 to prevent the support piece 3 from moving in the surface direction of the outer frame 1.

Thus, the support piece 3 is removably attached to each through hole 2 of the outer frame 1 to form the frame member 4, and the bracket 11 and the bolts 11 and the bolts are provided at both ends of the frame member 4 as shown in FIG. It is connected to an endless chain 13 by a nut 12. The chains 13 are also parallel to each other on the right side in FIG. 2, the frame members 4 are connected to the chains 13 at both ends, and a large number of frame members 4 are connected at equal intervals in the longitudinal direction of the chain 13. It constitutes an endless conveyor.

As the chain 13, a roller chain is used here, which is connected to a well-known drive device (not shown) so as to travel on the rail 15 of the machine body 14. It should be noted that this traveling is not meandered by a guide (not shown). The fact that the endless conveyor is formed by coupling the framing member 4 and the chain 13 is known, and will not be described in detail. In this way, the cup-shaped or donburi-shaped containers are engaged with the holes 6 of the support pieces 3 and conveyed, but as an endless conveyor, the number of rows corresponding to the number of the support pieces 3 in one frame member 4 forms a container. Will be transported.

When removing the support piece 3 from the outer frame 1, the support piece 3 is taken out in the upper surface direction of the outer frame 1 while slightly deforming the tongue piece 9 inward of the hole 6. When the tongue piece 9 is deformed as described above, the claw 9a is disengaged from the back surface of the outer frame 1 and the mounting of the support piece 3 on the outer frame 1 is released. Therefore, when the shape or size of the container supported by the support piece 3 changes, the support piece 3 having the holes 6 corresponding to the shape and size of the newly supported container as shown in FIG. It is prepared and attached to the outer frame 1. As a new supporting piece 3 in this case, it is preferable to use the same plate material 5, guide 8 and tongue piece 9 as the original supporting piece 3, but like the original supporting piece 3 described above. Anything that can be worn is acceptable. The new support piece 3 shown in FIG. 4 differs from the original support piece 3 shown in FIG. 1 only in the size of the holes 6.

As described above, by exchanging the support piece 3 with respect to the outer frame 1, it is possible to cope with a change in the object to be conveyed without exchanging the outer frame 1, the chain 13 and the like. FIG. 5 is for explaining the action of the width across flats 7a in the ridge 7 of the hole 6 of the support piece 3. That is, the container 16 is supported by the support piece 3 by engaging the upper end flange 16a of the container 16 with the upper surface of the ridge 7 of the hole 6, and the paper-like lid 17 is adhered to the upper surface of the flange 16a of the container 16. ing. This is well known as a lid for instant noodle containers and the like. The lid 17 is formed with a tongue-shaped knob portion 17a for the convenience of peeling it off. However, when the lid 17 is wrapped with a heat-shrinkable film in a later step, the knob portion 17a is projected. Since it interferes with the packaging, it is required to fold it down during the manufacturing process. Here, one of the two flat width portions 7a of the convex shape 7 is used to fold the grip portion 17 downward by a device (not shown). Since it is a flat surface different from the peripheral surface, and therefore the upper end of the flat width portion 7a forms a straight line, it is possible to fold the grip portion 17a at this straight portion and press it against the flat width portion 7a. Then, the grip portion 17a of the lid 17 is folded as desired. Although not shown, the right end of the lid 17 in FIG. 5 is flush with the right end of the flange 16a.

The above description has been made assuming that the endless conveyor of the present invention is used in the manufacturing process of food products in containers. However, the endless conveyor to which the present invention is applied is not limited to containers other than food, and items other than containers. Needless to say, it may be one that conveys. Further, in the above-mentioned embodiment, the convex shape 7 is formed around the hole 6, but it goes without saying that the convex shape 7 may be omitted.

[0016]

[Effect of the device]

 As described above, in the present invention, when a conveyor that was carrying an article of a certain shape and size was used to carry an article of another shape or size, the support used up to that point was used. Remove the piece from the outer frame and attach a new support piece with holes corresponding to the shape and size of the new item to the outer frame so that the same conveyor can be used to Since an item of a shape or size can be transported, the effect that another item can be easily transported at a lower cost than in the case of exchanging the entire conveyor or the frame material. is there.
