Abstract

PURPOSE:To make a conveyor manufacturable inexpensively even in the case where the positional relations and the like of a guide deffer, by separating it into a conveying part having the conveying guide adjusted to size of a conveyed body and a space holding part of a conveyor body frame in a fixed form unaffected by the conveyed body size. CONSTITUTION:A conveying part 21 consisting of conveying and returning guides 10a and 10b, a wiring duct 12, an air charging pipe line 13, etc., is clamped to a conveyor body frame 14 as being easily detachable with a bolt 15. In addition, the guide 10b of holes 16 and 17 in the frame 14 constituting a holding part 22 and a hole 16 of the duct 12 both are provided with each sufficient space, so that when a method of the guide 10b is altered by size of a pallet 8, the frame 14 is installed there whereby pliable accommodation is made attainable.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a conveyor II for conveying 7 objects to be conveyed.

BACKGROUND OF THE INVENTION In recent years, conveyor equipment has occupied an important position with the rapid advancement of factory automation.

An example of a conventional conveyor device will be described below with reference to the drawings.

FIG. 3 shows an overall outline of a conventional conveyor device. In FIG. 3, 1 is a pallet, and 2 is a workpiece placed on the pallet 1. 3a.

3b is a conveyance guide that mills the posture of the pallet 1, 3a is for conveyance, and 3b is for return. Transport guide 3
a and 3b also serve as guides for the chain 4 that transmits conveying force to the pallet 1. Reference numeral 5 indicates a wiring duct for storing electrical wiring, and reference numeral 6 indicates an air supply pipe for supplying air to the conveyor-related equipment and the pneumatic equipment of the automatic machine. Reference numeral 7 denotes a conveyor body frame, which is made of a steel plate processed to match the shapes of the conveyance guides 3a, 3b, the wiring duct 5, and the air supply piping 6.

In the conventional conveyor device configured as above,
The pallet 1 on which the workpiece 2 is placed is stopped and regulated at an arbitrary working position during the process of being transported on the transporting guide 3a, and undergoes the work. This operation is repeated several times, and when the operation is completed, work 2 is taken out and empty pallet 1 is removed.
Only the returned items are sent back on the return guide 3b.

Problems to be Solved by the Invention However, in the conventional conveyor device as described above,
The shape of the transport guides 3a and 3b may differ depending on the dimensions of the object to be transported (pallet 1 in the above example), or the transport guide 3 may have different shapes.
If the positional relationship between a and the return guide 3b is different, it is necessary to design and process the conveyor body frame 7 according to this shape as needed, which increases the cost of the conveyor device, and when changing the model, etc. There was a problem in that the conveyor body frame 7 had to be remanufactured when the dimensions were changed.

In view of the above-mentioned problems, the present invention provides a conveyor device that can be constructed at low cost even when the dimensions of the objects to be transported and the positional relationships of the transport and return guides are different.

Means for Solving the Problems In order to solve the above-mentioned problems, the conveyor mounting of the present invention has a conveyance guide that has a different shape depending on the size of the conveyed object, and transmits conveyance force to the conveyed object. A conveyor body frame having a constant shape regardless of the dimensions of the conveyed object; and a holding part to which the conveyor body is removably fastened to a fastening part. be.

Effects The present invention has the above-described configuration, which separates a portion that depends on the dimensions of the conveyed object and a portion that does not, and adjusts the shape of the conveyor main body frame to the dimensions of the conveyed object and the positional relationship of the conveyance and return guides. By keeping the conveyor body frame constant, it is possible to maximize the production of the conveyor main body frame, realize the conveyor device at low cost, and also be able to flexibly respond to changes in the dimensions of the conveyed object due to changes in the model, etc.

EXAMPLE Hereinafter, a conveyor apparatus according to an example of the present invention will be described with reference to the drawings.

FIG. 1 shows an overall outline of a conveyor device according to a first embodiment of the present invention. In FIG. 1, 8 is a pallet as an object to be transported, and 9 is a workpiece placed on the pallet 8. Reference numeral 10a indicates a transport guide, and 10b indicates a return guide, which also serves as a transport guide. These guides 10a and 10b are connected to the pallet 8
The chain 11 that transmits the conveying force to the pallet 8 is guided. 12 is a wiring duct, and 13 is an air supply pipe. The transport section 21 is configured as described above.

14 is a conveyor body frame, and conveyance guide 10a
, 10b, wiring duct 12 and air supply piping 13
are fastened with bolts 15 as fastening parts so that they can be easily attached and detached. The conveyor body frame 14 is made of a thin steel plate, and is provided with holes 16° and 17 through which the return guide 10b, the wiring duct 12, and the air supply wiring 13 pass. As shown in FIG. 1, the return guide 10b
The holes 16 for the wiring ducts 12 and 12 are provided with sufficient space to cope with the case where the dimensions of the return guide 101) change depending on the dimensions of the pallet 8. The holding portion 22 is constituted by these.

FIG. 2 shows an overall outline of a conveyor device according to a second embodiment of the present invention. In FIG. 2, the return guide 10b is on the same plane as the transport guide 10a,
It is attached to the support member 1B which is fastened to the conveyor body frame 14 with bolts 15. In this case as well, the same conveyor body frame 14 as in the first embodiment can be used.

As described above, according to this embodiment, by providing the conveyor body frame 14 which has a constant shape regardless of the dimensions of the pallet 8, the dimensions of the pallet 8 and the positions of the conveyance and return guides 10a and 10b can be adjusted. ! We can respond flexibly even when the relationship is different.

Effects of the Invention As described above, the present invention has a transport section having a transport guide having a shape different depending on the dimensions of the transported object, a drive device for transmitting a transport force to the transported object, and a In addition to having a conveyor main body frame that has a constant shape regardless of dimensions, the conveyor section also includes a holding section that is removably fastened with fastening parts, so that the dimensions of the objects to be conveyed and the conveyance guide can be easily adjusted. A conveyor device with different mounting positions can be realized at low cost and with flexibility.
