Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device that is capable of conveying in multiple directions using a conveying body in which a large number of conveying blocks are chained together.

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 direction of transfer. Must. Further, although roller conveyors enable curved conveyance, their structure is complex and extremely expensive. Furthermore, although chain conveyors enable transfer in multiple directions, the allowable range of load is small, and when the chain is stretched, the short links that make up the chain must be positioned alternately. They have to be aligned, are time-consuming to assemble, are prone to failure, and have the drawback of constantly producing frictional noise between the shot links, which can be a source of noise.

The present invention aims to eliminate the drawbacks of these conventional devices by configuring 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 in multiple dimensions.

Another object of the present invention is to protrude a guide rod having an escape prevention piece from the center position of the lower surface of the conveyor block forming the conveyor, and to attach the guide rod to the bottom surface of the travel path. On the other hand, by inserting and supporting the robot so that it can run freely in the travel guide groove provided along the travel path, it can be freely transported in multidimensional directions according to the travel path formed as appropriate by the left and right travel guide plates. The purpose of the present invention is to provide a transport device that can move a body.

Furthermore, another object of the present invention is to form tooth profiles on the outer peripheral surfaces of the driving pulley and the driven pulley provided on both sides of the travel path, and to provide a conveying block for feeding each conveying block forming a conveying body in the tooth profile. To provide a conveyance device that can efficiently run a conveyance body without slipping due to the rotation of the drive pulley by fitting the projections and stretching the conveyance body between a drive pulley and a driven pulley. It is.

Furthermore, another object of the present invention is to provide an insertion hole located in the center of the conveying block and penetrating in the front-rear direction and having a latching recess on the inside, and the insertion hole is divided into upper and lower parts. By dividing the transport block into upper and lower parts as shown in FIG. If a large number of transport blocks, which are divided into upper and lower parts so as to fit into the recesses, are stacked and attached to form a single unit, the large number of transport blocks are arranged in a daisy chain and have flexibility.

The connecting member 16 can be made as a whole, but various types such as a straight member, left and right curved members, and upper and lower curved members can be made in advance and used as needed. It is advisable to connect these parts by hand to assemble the traveling path 14 of a desired shape. 18 is a running guide groove, and the running path 1
A guide rod 6 protruding from the center of the lower surface of the conveying block 2 constituting the conveying body 1 is provided along the traveling path 14 on a member forming the bottom of the conveying body 1, such as the connecting member 16. They fit together freely. Reference numeral 19 is a guide latch groove for supporting the escape prevention piece 7 protruding from the guide rod 6, and is located inside the travel guide groove 18 and formed to bulge. 20 is a drive pulley, which is connected to the traveling path 1
4, and is rotationally driven by a motor 23 or the like disposed outside the traveling guide plate 8. This driving pulley 20 has an outer circumferential groove 21 in the center of its outer periphery into which guide rods 6, 6, etc. protruding from the center of the lower surface of the conveying blocks 2, 2, which constitute the conveying body 1, can be fitted. At the same time, locking recesses are provided at equal intervals on the outer peripheral edge portions located on the left and right sides to form tooth shapes 22, and transport blocks 2, 2, . . .

Conventional conveying devices require a number of conveying devices whose direction changes according to a change in the direction of movement,
A large space was required to install these transport devices. However, according to the present invention,
By configuring a flexible conveying body in which a large number of conveying blocks are chained together by wires, the moving direction can be freely changed in multiple dimensions.

Further, according to the present invention, guide rods having an escape prevention piece are formed protrudingly at the center position on the lower side of the transport block forming the transport body, and these guide rods are aligned along the travel path with respect to the bottom surface of the travel path. By being configured to be inserted and supported so as to be freely movable in the provided travel guide groove, 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 travel path, and the feeding protrusions of each conveying block forming the conveying body are fitted into these tooth profiles. By disposing the conveying body between the driving pulley and the driven pulley, there is a practical benefit that the conveying body can run efficiently without slipping due to the rotation of the driving pulley.

Furthermore, according to the present invention, the conveying block is provided with an insertion hole that is located in the center of the conveying block and has a locking recess on the inside that penetrates in the front-rear direction, and that the insertion hole is divided into upper and lower parts. Since it is formed into upper and lower parts, a large number of latching spherical bodies are arranged at equal intervals on the wire, and these latching spherical bodies fit into the latching recesses of the insertion holes in the transport block. By stacking a large number of transport blocks that are divided into upper and lower parts and attaching them in a unified manner, the large number of transport blocks can be arranged in a daisy chain, making it extremely easy to construct a flexible transport body. It has real profits that can be formed.

Furthermore, according to the present invention, the insertion hole provided in the conveyance block is provided with a latching recess, so if two latching recesses or two latching recesses are provided in succession, the wire can be Since the latching spheres provided on the terminal parts can be fitted into the latching recesses from both the left and right sides of the insertion hole, both terminal parts of the wire can be connected extremely easily and connected endlessly. It has practical benefits that can be achieved.

Therefore, according to the present invention, a large space is not required for installing the conveying device, the factory layout becomes easy, and the conveying device can be installed freely according to the arrangement of existing machine tools.
