Abstract

PURPOSE:To facilitate the work of shifting corner members and the like and prevent the members from being damaged by setting the work loading face of a tray and those of two work lines on the same plane when the tray having a workpiece placed thereon and on its way through a curing furnace is located halfway between the two work lines while on a truck. CONSTITUTION:An adhesive is applied to a mating surface 16 of a corner member 11 on a work line 1 and then the member 11 is shifted from the work line 1 onto a tray 8 on a traverser 3. This shifting work is accomplished simply by sliding of the member 11, since the work loading face of the work line 1 and that of the tray 8 on both of which workpieces are loaded by respective groups of rollers are located on the same plane. When the shifting work is completed the traverser 3 starts to move and then stops when reaching a position Y and also a conveyor 9 is driven. With this operation, the tray 8 is shifted from the traverser 3 onto a tray conveyance passage 5 with the member 11 thereon and is moved along the conveyance passage 5 and is shifted onto a traverser 4 after passing through a curing furnace 10.

Further, two rows of tray transport paths 5 and 6 are arranged parallel to the processing lines 1 and 2. The tray conveyance paths 5 and 6 pass through a conveyed object curing furnace 10, and one end portions 5a and 6b of each are located on a line along the exit 1a of the processing line 1. Conveyors 51...51, 61...61 are provided at the top of each tray conveyance path 5, 6, respectively, and the flow direction of the tray conveyance path 5 closer to the processing line 1 is opposite to the flow direction of the processing line. The flow direction of the other tray conveyance path 6 is the forward direction of the processing line.

On the other hand, a traverser 3 is arranged between the two processing lines 1 and 2. As shown in the side view of FIG. 3, this traverser 3 is provided with a conveyor 9 at the top and wheels 13 at the bottom. The traverser 3 is moved along two rails 14 laid on the floor by a drive mechanism (not shown) composed of a chain, a motor, etc. in a direction perpendicular to the flow direction of the processing line (described later). It is configured to move in parallel with the operation and sequentially locate at each point: a position X that coincides with the processing line 1, and positions Y and Z that coincide with the two rows of tray transport paths 5 and 6, respectively. Furthermore, the conveyor 9 above it
Based on the procedure described later, when the traverser 3 is at position Y, the traverser 3 is driven in the same direction as the flow of the tray transport path 5 for a predetermined time, and when it is at position Z, it is driven in the same direction as the flow of the tray transport path 6. It is configured to be driven only for a predetermined period of time. Note that when the traverser 3 is at position X, the conveyor 9 remains stopped.

Similar traversers 4 and rails 14 are also arranged at the other ends 5b and 6a of the two rows of tray conveyance paths 5 and 6, and the traversers 4 operate under the operation described below. Two points, M and N, which coincide with tray transport paths 5 and 6, respectively, are moved alternately. Further, the traverser 4 is provided with a conveyor (not shown) similar to that described above, and as will be described later, when the traverser 4 is at the position M, this conveyor runs in the same direction as the flow of the tray transport path 5, and at the same position. When it is in the N position, it is configured to be driven in the same direction as the flow of the tray transport path 6 for a predetermined time.

Next, the operation of the embodiment of the present invention will be explained together with the processing procedure and the operation of each part. First, at the start of the procedure, the traverser 3 is waiting at position X, and in this state, the tray 8 is placed on top of it, as shown in FIG. Further, the traverser 4 is waiting at position M without any tray placed thereon. Now, after applying adhesive to the bonding surface 16 of the corner member 11 on the processing line 1, the corner member 11 is transferred from the processing line 1 to the tray 8 on the traverser 3. This transfer work is possible because the workpiece loading surfaces of the respective roller groups of the processing line 1 and the tray 8 are on the same plane.
This can be done simply by sliding 1.

Next, when the above-mentioned transfer work is completed, the traverser 3 starts moving, first stops its movement when it reaches the position Y, and moves the conveyor 9.
is driven. With this operation, the tray 8 is moved to the corner member 1.
1 is transferred from the top of the traverser 3 onto the tray conveyance path 5, and then transferred along the conveyance path 5, passing through the curing furnace 10, and then transferred onto the traverser 4. .

The traverser 4 stops driving the conveyor when the tray 8 is completely transferred to the upper part of the traverser 4, then starts moving, and stops the movement when it reaches the position N, and stops driving the conveyor. Start. By this operation, the tray 8 is transferred from the top of the traverser 4 to the tray conveyance path 6, transported by this conveyance path 6, and placed in the curing furnace.
It will be carried back into 0. At this time, the traverser 3 moves to position Z and is on standby, and the tray 8 that has passed through the curing furnace 10 is transferred onto the traverser 3. Further, the traverser 4 moves to the position M when the transfer of the tray 8 to the conveyance path 6 is completed.

Next, the traverser 3 stops driving the conveyor 9 when the tray 8 is completely placed on top of the traverser 3, and returns to position X with the tray 8 still placed thereon. As a result of the above operations, the corner member 11 is placed on the tray 8 and passes through the high-temperature curing furnace 10 back and forth, which causes the adhesive applied to the bonding surface 16 of the corner member 11 to be harden. Then, the corner member 11 that has undergone this curing treatment is sent out from the tray 8 onto the next processing line 2 by a slide, and subsequently, the next new corner member 11 is transferred from the processing line 1 onto the tray 8. move it to Thereafter, similar operations are repeated one after another.

Here, the moving operations of the traversers 3 and 4 and the driving operations of their respective conveyors as explained above are as follows.
Traverser detection sensors are placed at appropriate locations at positions X, Y, Z and M, N, and tray detection sensors, etc. are placed at the upper positions of traversers 3 and 4, and traverser detection is performed based on the outputs of these sensors. This can be easily implemented using known techniques by sequentially controlling the drive mechanisms 3 and 4 and their respective conveyor drive mechanisms.

In the above-described embodiment of the present invention, if an empty stage for one tray 8 is provided on the traversers 3 and 4 and the tray transport paths 5 and 6, a desired plurality of trays can be placed on the curing line. It is also possible to circulate the trays of the stand.

[0017]

[Effects of the Invention] As explained above, according to the present invention, the tray on which the workpiece is placed and passed through the curing furnace is
When placed on a cart such as a traverser and positioned between two processing lines, the workpiece loading surfaces of the tray and the two processing lines are arranged to lie on approximately the same plane, and the tray and the two processing lines are Since a group of rollers is provided on each of the loading surfaces of the two processing lines, it is now possible to transfer, for example, a corner member, etc. after adhesive has been applied, from the processing line onto the tray by simply sliding it without lifting it. The work can be easily performed and the corner members can be prevented from being damaged. In addition, after the corner parts after curing are sent out from the tray to the processing line,
Since the next new corner member can be placed on the tray without moving the tray, the time required to place and unload the corner member onto the tray can be shortened compared to the conventional method.

Furthermore, since the trays are automatically circulated and conveyed in a closed loop formed by a reciprocating conveyance path passing through a traverser and a curing furnace, corner members etc. to which adhesive has been applied first are cured. This makes it possible to apply adhesive to the next new corner member immediately, eliminating unnecessary work and improving productivity.
