Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pallet conveying device, and is particularly suitable as a pallet conveying device for loading shaped materials in a U-shaped automatic alumite film processing device for aluminum sash shapes. related to a transport device.

[Conventional technology]

Conventionally, the alumite film treatment process for aluminum sash window frames and other shapes has been carried out through a preliminary treatment process, a main treatment process related to the alumite treatment, and a post-treatment. In such processing steps, pallets are used to carry fabric materials into the process system and carry products out of the process system.

[Problem that the invention seeks to solve]

In order to automatically process a large amount of long aluminum sections, etc. in the process described above, it is necessary to load them onto pallets, carry them into the system, unload them, transport the sections individually, and then use the transport frame. It requires a number of steps, such as hanging the product on a stand, removing it, anodizing it, removing it from the transport frame, loading it onto a pallet again, and transporting it out of the system, but there is a need to make these processes fully automatic and complete in a small amount of space. There is. In response to this, a U-shaped process line as seen in, for example, Japanese Unexamined Patent Publication No. 55-38903 has been proposed, but no consideration has been given to the loading and unloading of pallets.

In recent years, there has been a demand for greater automation and faster processing in the loading and unloading of pallets, and there has been a demand for process equipment that can better utilize space in narrow factories. In addition, we have discovered that the pallet a feed route can be rationalized by making it possible to use an empty pallet after carrying in fabric materials as a valet/'r for carrying out products on the line, and propose the present invention. reached.

[Means for solving problems]

The present invention solves the above problems and utilizes space by disposing a pallet conveying device for carrying in pallets loaded with dough shapes and collecting empty pallets below various devices, and also for moving pallets from the conveyor to the side. Valet I-1, which can be moved freely and automatically to the pallet, and which can load the shapes onto the pallet or transfer the shapes on the pallet? It was developed with the primary purpose of providing a transmission device,
Furthermore, a second object of the present invention is to provide a pallet conveying device that can bypass the main pallet path to form a subpath that can be used as a product delivery pallet by bypassing the empty pallet. (1) The outbound conveyor and the return conveyor are arranged in parallel and connected, and the end of the return conveyor is connected.

A pallet stacking device is provided, and the pallet stacking device has a pair of conveyor devices perpendicular to the return conveyor on the upper part, an elevating platform inside, and a moving device on the elevating platform that advances and retreats in the direction of the return conveyor. A pallet conveying device having.

In addition, an outbound conveyor and a return conveyor are arranged side by side, and a movable elevator is installed at the end of the outbound conveyor so as to be movable in the direction of the return conveyor, and at the end of the return conveyor, the pallet on the return conveyor is scooped up and transported to the outside. A pallet conveyance device comprising: a pallet stacking device for carrying out; and a pallet bypass device disposed at the intermediate portion of the return conveyor directly below the product conveyance mechanism above the longitudinal intermediate portion of the return conveyor.

It is configured as follows.

[Effect]

A pallet loaded with dough shapes is placed on the outbound conveyor and carried into the system, and a return conveyor carries empty barres and throats to be carried out of the system. By disposing a pallet stacking device at the end of the return conveyor, empty pallets on the return conveyor can be moved to the outside and stacked. In other words, in the mallet stacking device, the moving device moves below the empty pallet, and when the lifting platform rises, the moving device moves onto the lifting platform with the empty pallet still on it,
Next, when the lifting platform is lowered, the empty pallet can be placed on the unloading conveyor. By repeating this process, more empty pallets can be stacked on top of the empty pallets on the carry-out conveyor, and by moving and rotating the carry-out conveyor by the width of one pallet in the stacked state, empty pallets can be stacked on top of the carry-out conveyor. can be done.

In addition, for example, when you want to urgently perform unscheduled loft processing, you can place the sections on the conveyor of the pallet stacking device, raise the lifting platform, and place the sections on the moving device. It is also possible to load the sections onto the pallet by moving the moving device onto the empty pallet on the return conveyor and lowering the lifting platform. Furthermore, if there is a shortage of product loading pallets for the product traverser U line due to a delay in progressive transport from the outbound conveyor side for various reasons, empty pallets can be supplied from the main stacking device.

In addition, since a barre/nod bypass device is installed in the middle of the return conveyor, it eliminates the need for the outbound conveyor used to carry in product loading pallets on the product out-of-system delivery line in the conventional method, and also makes it easier to prepare for the entire process. The number of pallets to be processed can be reduced.

At that position, the height of the loading arm 20E is set to be such that it can fit under the bottom of the pallet P stopped on the return conveyor C. In Fig. 2, when an empty pallet is sent from the mobile elevator G to the end edge of the return route by A C to the return route container,
The chain conveyor automatically stops and enters the state shown in the front view shown in FIG. Here, when the motor 22 is rotated in the forward direction to move the chassis 20B forward in the direction of the pallet P, the mounting arms 20E and 20E enter under the bottom of the pallet P, as shown in plan in FIG. Therefore, when the cylinder 16 is actuated to raise the elevator platform 17, it will be in a state as shown in the front view in FIG. Here, the motor 22 is reversely rotated to

FIG. 13 is a side view taken from the I-1 line direction in FIG. 1. To explain the operation with reference to FIG. 1 and FIG. 13, the pallet P that has been conveyed to the end of the outbound conveyor device B is transferred to the movable elevator G with the fabric shapes X loaded thereon. The mobile elevator G is provided with a conveyor 23 at the top for transferring empty pallets to the return conveyor device C. The mobile elevator G has wheels 24, 24... mounted on its lower part,
The wheels 24, 24, . . . can move left and right in the drawing on rails 25 on the base, and this movement is performed by the actuation of cylinders 26 disposed on the base.

In addition, the mobile elevator has a cylinder 27 in the central part of the plane.
A lifting platform 28 is provided which can be raised and lowered.

Therefore, when the lifting platform 28 is raised after the mobile elevator G is moved toward the return conveyor device C, the fabric shapes X on the pallet P are lifted above the pallet P. At that stage, the dough profile X is scooped up from the lifting table 28 with the fork 30 of the conveyor 29.

The conveying machine 29 has a fork 30 suspended from a cart 31 that slides on rails 32, and conveys the section X to the upper part of the machine J.

At the stage when the tilting table 37 is tilted, the spacer interposed between the top and bottom of the dough shape falls into the hopper Ka and is collected by the conveyor Kb.

On the other hand, the empty pallet P due to the reloading of all the fabric forming materials is transferred onto the return conveyor C by operating the conveyor 23 of the mobile elevator G, and then transferred to the return conveyor C.
is activated to convey it to the terminal edge. After the empty pallet is transferred, the cylinder 26 of the mobile elevator G is moved backward to make it wait on the outbound conveyor side.

Next, the pallet bypass device E is installed as shown in FIGS. 14 to 16.
This will be explained using figures.

The pallet bypass device E is a device in which an empty pallet P is conveyed to the terminal side by an outgoing conveyor C, and a part of the empty pallet is bypassed onto the path of the product traverser U for product loading as needed. To eliminate the need to install a separate empty pallet supply line for carrying out products.

The structure of the pallet bypass device E is almost the same as that of the above-mentioned pallet stacking device, but it consists of a pallet take-up mechanism section 40 and a pallet stock conveyor section 60.

The pallet take-up mechanism section 40 is for taking over a part of the pallet from approximately the middle part of the return conveyor C (directly below the product conveyance mechanism F), and is arranged parallel to the longitudinal direction of the return conveyor C. Parallel links 4 for maintaining the lifting table 43 horizontally are provided on both sides in the longitudinal direction of the lifting table 43 which moves up and down via cylinders 42 on a base 41 which is shaped like a
4.44 is installed.

The parallel link 44 is made up of a pair of link plates 45A and 45B, and its longitudinal center portion is pivotally attached to a shaft 46, so that the side surface can be opened and closed in an X-shaped cross section. The inner link plates 45B, 45B on both sides have their lower ends pivoted and fixed to the base 41, and have guide guides 47 pivoted to their upper ends. It is slidably fitted into a horizontal guide rail 48 having a U-shaped cross section.

Also, outer link plates 46A on both sides.

46A has an upper end pivoted and fixed to the side of the guide rail 48, and a lower end pivoted to a guide port 47, each of which has a U-shaped cross section formed on the upper side of the base 41. It is slidably fitted onto the rail 49.

With the above configuration, the base 4 when the lifting platform 43 moves up and down
1 is maintained. These link mechanisms can be of the same form as those of the pallet stacking device described above.

A pair of mounting arm mechanisms 50 are provided on the upper part of the lifting table 43.
are arranged as shown in FIGS. 15 and 16. Each mounting arm mechanism 50 includes a vehicle platform 52 and a cough platform 5 on which a mounting arm 51 that is longer than the width of the pallet is protruded.
It consists of a drive section 55 that operates 2.

The chassis 52 is slidably fitted into guide rails 54 which are oppositely provided and have a U-shaped cross section through a guide shaft 53 connected thereto. Further, the chassis 52 is connected to a chain 56 of a drive unit 55 by an engaging member at the lower part thereof, and is moved forward or backward by transmitting forward and reverse rotation of the motor 57 to the chain 56 through a timing chain or the like. That is, by advancing the vehicle to the return conveyor C side, the loading arm 51 is passed under the barre throat that is stopped at the same position on the return conveyor C, and then the link mechanism is activated to lift the pallet. Thereafter, by reversing the vehicle platform 52, the operation of picking up the pallet on the return conveyor C is completed, and the pallet is delivered to the pallet stock conveyor section 60.

The pallet stock conveyor 60 can be constructed as an integrated conveyor section, but by configuring it as two conveyor sections 60A and 60B as shown in FIGS. Efficiency can be further improved. That is, by adopting the two rules, it becomes possible to carry out the work of picking up the pallets from the return conveyor C and the work of supplying the pallets to the product traverser U in parallel.

The conveyor section 60A includes a drive shaft 6 connected to a motor 61.
2 and a driven shaft 63 are wound around a chain conveyor 64, and the conveyor 608 is also formed by winding a driving shaft 67 and a driven shaft 68 connected to -11--65 around a chain conveyor 69. The chain conveyor 69 also functions as a stockyard for empty pallets that are bypassed for product loading.

The pallet stock conveyor section 60 picks up the empty pallet onto the loading arm 51, moves it backward at a predetermined interval, and then
By lowering the link mechanism of the lifting platform 43, the empty pallet is transferred onto the conveyor section 60A, and then the motor 61 is operated to transport the empty pallet forward, and the mokuro 5 is further actuated. By the operation procedure of transferring the pallet onto the conveyor section 60B, the empty pallet on the AC can be bypassed to the return conveyor, and the stock function can be fulfilled.

The present invention configured as described above is a pallet conveying device that constitutes a part of an automatic alumite film processing device, and can automatically function to convey pallets loaded with fabric shapes and collect empty pallets, and can also be used in narrow spaces. Since it can also be arranged three-dimensionally, space can be used effectively, and the high-speed automatic processing capacity of the entire automatic alumite film processing apparatus can be improved.

The pallet stacking device is suitable for space utilization because it can automatically stack and stock empty pallets in a tiered manner.

In addition, the pallet bypass device has the same configuration as the Habo pallet stacking device, and is installed approximately in the middle of the return conveyor. The pallet line for carrying out products can be simplified.

The drive system of each piece of equipment is connected to a separate automatic control switchboard, and is controlled by an automatic control system that coordinates with the functions of the entire process equipment.
