Abstract

PURPOSE:To convey articles in multi-dimensional directions by providing conveyer blocks having the front and rear edge portions slightly tapering on both right and left sides, which are provided with a guide rod with a drop preventing piece and tied in a row by a wire to be driven endlessly. CONSTITUTION:Conveyer blocks 2 having the front and rear edges slightly tapered on left and right sides and provided with a guide rod 6 with a drop preventing piece 7 and a feed projection 5 are fixed by inserting a wire in an insertion hole 8 and tied in a row to form an endless conveyer 1. Thus, even if the conveyer 1 is laid in a curved line, the edges of the blocks 2 are kept from interfering with each other by the taper surfaces 4, so that the conveyer 1 can be driven to guide by the guide rods 6. If the front and rear side surfaces of the block 2 are formed, with the central part expanded, a track curved vertically can be attained. Thus, articles can be conveyed in multi-dimensional directions.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyance device that enables conveyance in multidimensional directions using a conveyance body in which a large number of conveyance blocks are connected in a daisy-like manner.

Conventionally, belt conveyors, roller conveyors, chain conveyors, and the like are generally known as conveyance devices.

Of these, belt conveyors are the most widely used because of their simple structure, but their transfer is limited to a linear range, and multiple belt conveyors are used in combination to change the transfer direction. Must.

Curved roller conveyors enable curved conveyance, but their construction is complex and extremely expensive. Furthermore, although chain conveyors enable conveyance in multiple directions, the allowable load range is small, and when the chain is stretched, the short links that make up the chain are placed in alternating directions. They have to be arranged in the same way, are time-consuming to assemble, are prone to failure, and have the disadvantage of producing frictional noise from the IJ (IJ), which can be the source of the noise.

The present invention aims to eliminate the drawbacks of these conventional devices, and has been developed by constructing a flexible conveying body in which a large number of conveying blocks are connected in a daisy-like manner with wires. The present invention provides a conveyance device that can freely change the direction of conveyance over multiple dimensions.

Yet another object of the present invention is to protrude guide rods having an escape prevention piece from the center position of the lower surface of the conveyor block forming the conveyor body, and to attach these guide rods to the bottom surface of the travel path. On the other hand, by inserting and supporting the conveyor so that it can run freely in the travel guide groove provided along the travel path, the conveyor can be moved freely in multidimensional directions according to the travel path formed by the left and right travel guide plates. The present invention provides a transport device that can be moved.

Furthermore, another object of the present invention is to form tooth profiles on the outer circumferential surfaces of the driving pulley and the driven pulley provided on both sides of the traveling path, and to provide a means for feeding each conveying block forming a conveying body in the tooth profile. The purpose of the present invention is to provide a conveying device in which the conveying body is tensioned between a driving pulley and a driven pulley by fitting protrusions, so that the conveying body can run efficiently without slipping due to the rotation of the driving pulley. be.

That is, the present invention provides a conveying block whose front and rear side edges are slightly tapered toward the left and right sides, and provides feeding protrusions located on both sides on the lower surface of the conveying block, and has feeding protrusions located in the center. A guide rod with a piece to prevent escape is formed in a protruding manner, and a large number of the conveying blocks are arranged in a daisy chain shape with respect to an endless wire to form a conveying body, and the left and right traveling guide plates The traveling path of the carrier is formed endlessly, a driving pulley is provided at one end of the traveling path, and a driven pulley is provided at the other end, and tooth profiles are formed on the outer peripheral surfaces of the driving pulley and the driven pulley. The transporting body is stretched between the driving pulley and the driven pulley by fitting the feeding protrusions of the transporting blocks, and a running guide groove along the running path is provided on the bottom of the running path to allow each transporting block to The gist of the present invention is a structure of a conveyance device characterized by a guide rod that is inserted and supported so as to be freely movable.

Next, the conveying device of the present invention will be explained according to the illustrated embodiment. (1) is a conveying body, and a wire (3) is made up of an endless number of conveying blocks (21F2). It is constructed by connecting them in a daisy-like manner. The transport block (2) is made of synthetic resin, metal, etc., and has two flat sides,
Slanted surfaces (4) are provided so that the front and rear side edges thereof are slightly tapered toward both left and right sides. The inclined surfaces (4) provided on the front and rear side edges on both the left and right sides make it easy for the conveyor (1), which is made up of these conveyor blocks (2) F2) connected in a daisy-like shape, to curve left and right. It may be straight or curved. However, if this inclined surface (4) is provided with an inclination more than necessary, it is inconvenient because a large gap will be created on both sides between the conveying blocks (2) F2) located in front and behind. Also,
If the front and rear sides of these transport blocks (2) (2)...° are formed as curved surfaces with a bulging center, these transport blocks (2+ (2)...

By being configured to be inserted and supported so as to be freely movable in the travel guide groove provided, the conveyor can be freely transported in multidimensional directions corresponding to the travel path appropriately formed by the left and right travel guide plates. It has practical benefits that can be achieved.

Furthermore, according to the present invention, tooth profiles are formed on the outer peripheral surfaces of the driving pulley and the driven pulley provided on both sides of the traveling path,
By fitting the feeding protrusions of each conveying block that forms the conveying body into these tooth shapes and tensioning the conveying body between the driving pulley and the driven pulley, the conveying body can be slid easily by the rotation of the driving pulley. It has the practical benefit of being able to run more efficiently.

Therefore, according to the present invention, there is no need for a large space for installing a conveyance device, the factory layout is easy, and the device can be freely arranged to match the arrangement of existing machine tools.
