Abstract

PURPOSE:To aim at facilitating the replacement of pallets, by storing a set of pallets in a storage conveyer disposed below a lower stage return conveyer so that when the pallets are required, the pallets are received and delivered between a working conveyer and the storage conveyer only during the first cycle. CONSTITUTION:When sets of pallets 2 are replaced with each other, that is, when pallets 2 stored in, for example, the lowermost stage storage conveyer 7 are required, a delivery side elevator 5 carries thereon pallets discharged from a working conveyer 1 to lower the pallets, and then feeds out the pallets onto the lowermost storage conveyer 7 while a delivery side elevator 4 carries thereon another set of pallets 2' which are protruded from the storage conveyer 7 and which are discharged therefrom, and moves them upward. Such a process is repeated until a set of pallets are completely replaced with those of another set. Thereafter, the elevators 4, 5 are moved up and down between the working conveyer 1 and the return conveyer 3, and then normal circulating conveyance takes place. Thus, it is possible to facilitate the replacement of pallets, and therefore, to aim at enhancing the ability of working.

(b) Prior art and its disadvantages As shown in Fig. 2, the pallet circulating conveyor places parts on a pallet 2 that is conveyed on a working conveyor l, and performs assembly and processing on these parts one by one. It was designed to do this. For this reason, after the pallet 2 on which parts are placed on the carry-in side completes the work process and the parts are carried out on the carry-out side,
It must be circulated again to the input side. Therefore, a return conveyor 3 is arranged at the lower stage of the work conveyor 1, and elevators 4 are installed at both ends of these conveyors 1.3.
, 5 are provided. The return conveyor 3 is a conveyor that conveys the pallet 2 in the opposite direction to the work conveyor 1. The elevator 4 on the carry-in side is a conveyor that carries the pallet 2 discharged by the return conveyor 3 and moves upward to deliver it onto the working conveyor 1. Moreover, the elevator 5 on the carry-out side is a conveyor that moves up and down on which the pallet 2 discharged from the work conveyor 1 is placed, moves downward, and is delivered to the return conveyor 3. Therefore, the pallet 2 is loaded with parts on the elevator 4, is transported over the work process by the work conveyor l, is carried out on the elevator 5, is transported again to the elevator 4 by the return conveyor 3, and is carried out in circulation. repeat.

However, in a work process using such a pallet circulating conveyor, the shape of the parts changes from lot to lot, and therefore different types of pallets 2 may have to be used. In this case, in the conventional pallet circulation type conveyor shown in Fig. 2, it is necessary to remove all the pallets 2 from the carry-in side or the carry-out side and then sequentially feed in new pallets 2 to change the type of pallets. Ta. For this reason, in the past, a changer or the like exclusively used for pallet exchange was required, which not only made the apparatus complicated and expensive, but also made the exchange work complicated and time-consuming.

When the present invention is configured as described above, it is possible to change the set of pallets being circulated by simply making the elevator perform a special operation during the first round, so there is no need for a device such as a changer for changing the structure. It can be done easily. Furthermore, since the pallets can be replaced while being sequentially conveyed on the work conveyor, lofts, etc. can be changed while parts are being continuously transported, with almost no time required for replacement. Furthermore, since unused pallets can be stored on each storage conveyor, it is possible to save space during work. Therefore, the present invention not only eliminates the need for a special device such as a changer, but also improves the workability of assembly work using a pallet circulating conveyor.

In the pallet circulation type conveyor of this embodiment configured as described above, during normal circulation work, the carry-in side elevator 4 places the pallet 2 discharged from the return conveyor 3 on the small conveyor 14. and move upwards to work conveyor 1.
At the same time, the elevator 5 on the unloading side transports the pallet 2 discharged from the working container hair 1 to the small container hair 1.
By repeating the operation of placing pallets 2 on pallets 5, moving them downward, and sending them out to return conveyor 3, one set of pallets 2 is repeatedly conveyed in circulation. A working process is constructed on this working conveyor 1. For example, in the case of the assembly process of a serial type thermal head, a flexible cable is supplied to the pallet 2 on the elevator 4, and as the work conveyor 1 transports the head, the resistance value of the heating resistor 1 is attached and soldered. Measurement and coating operations such as
The completed thermal gutter is carried out on elevator 5 and sent to the next drying process.

In addition, when changing the set of pallets 2, for example, if the pallets 2 stored on the lowest storage conveyor 7 are required, the elevator 5 on the carry-out side will collect the nocles and throats discharged from the work conveyor 1. The pallets 2' are placed thereon and moved downward to be sent out to the storage conveyor 7G at the lowest stage, and the pallets 2' of the set 2' which protrude from the storage conveyor 7 on the side of elevator No. 4 on the carry-in side and are discharged are placed thereon. The operation of moving upwards and sending it to the industrial conveyor 1 is repeated until one set of combs and combs are completely replaced. Then, the elevators 4 and 5 are moved up and down again using the working conveyor 1 and the return conveyor 3 in (1), and normal circulation conveyance begins.

It is possible to change the pair of pares and sotos to be sent. In addition, since this replacement is performed sequentially as the gutter and gutter 2 are circulated and conveyed, there is almost no time loss, and there is no need to stop the production line each time. Furthermore, unused pallets, 7to 2' and 2'' are each stored on a storage conveyor 6.
7, so there is no wasted space. Therefore, this embodiment can simplify the structure of the pallet exchange mechanism and improve the workability of the process using a conveyor.
