This invention relates to a conveyance device having a belt conveyor, in particular, a driving roller and a driven roller of the belt conveyor are provided on a movable frame, and the movable frame is movable forward and backward from a frame of a guide rail via the rollers. A reversible drive motor is provided on the movable frame to drive the belt conveyor stretched between the drive roller and the driven roller forward and backward, and sheets are provided at both ends of the belt conveyor. This invention relates to a conveying device that is integrated into a single unit and faces the corresponding unloading pallets.

<Prior art> As is well known, in a molding machine, for example, an injection molding machine, products and accessories such as runners are taken out one after the other, conveyed to the same conveyor, and sorted into product lines and collection courses. It is being done.

<Problems to be solved by the invention> Therefore, since the product is mixed with other molding accessories, there is a drawback that the product is easily damaged. A sorting process is required, resulting in extremely complicated work and an inconvenient increase in man-hours.
There was a drawback that it was difficult to automatically collect the runners.

Furthermore, when changing the molding equipment for a new product plan, there is a problem that the conveyor interferes with the replacement work and gets in the way.To deal with this, it is necessary to provide a considerable amount of space between each mechanical device. This had the disadvantage of requiring a large space for equipment.

The purpose of this invention is to solve the technical problems of the conveyor system that receives and receives products and accessories in one piece based on the above-mentioned conventional technology. An excellent conveyor device that benefits the application of conveyor technology in the molding industry by allowing automatic feeding of accessories, close conveyance, and free setup changes without interference. We aim to provide the following.

<Means and actions for solving the problem> In accordance with the above-mentioned purpose, the structure of this invention, which is summarized in the scope of the above-mentioned utility model registration claims, is to solve the above-mentioned problem. In a belt conveyor and a conveying device provided on a frame, the end of which faces the chute, the frame is formed into a pair of guide rails, and the front and rear parts of the movable frame are provided on the guide rails so as to be movable forward and backward via rollers. A driving roll and a driven roll are pivotally supported, a belt conveyor is provided between the driving roll and the driven roll, a reversible type drive motor for the input belt conveyor is provided on the movable frame, and furthermore, a reversible type drive motor for the input belt conveyor is provided at both ends of the belt conveyor. This is a conveying device in which a chute is provided in each section so that each chute faces the corresponding unloading pallet.

<Function> Then, the product and accessories such as runners are taken out one after the other in the molding device and transported onto a belt conveyor, which is driven by a reversible drive motor to transfer the products and accessories. The belt conveyor is rotated forward and backward in the order of delivery, and is sorted and delivered to the corresponding delivery pallets via the chute at both ends, and the drive roller and driven roller of the belt conveyor are supported when changing the molding equipment setup. The movable frame is retracted and moved relative to the guide rail, and at that time, the drive motor provided on the movable frame also moves together, making it possible to freely and smoothly change the molding equipment setup. The measures were taken.

<Example> Next, an example of this invention will be described below based on the drawings.

Reference numeral 1 denotes a conveying device which constitutes the gist of this invention, and is attached to a well-known injection molding device 2 as a molding device. A take-out machine 7 is provided as a loading device for taking out the product 5 and a runner 6 as an accessory, and the slider 8 slides a side arm 10 via a moving device 9 to remove the product 5 from the injection molding device 2. runner 6
is transferred onto a belt conveyor 11 and dropped.

Note that the forward and reverse rotation of the take-out machine 7 and the belt conveyor 11 is performed synchronously.

Thus, the device main body 12 of the conveying device 1 has the third and fourth
As shown in detail in the figure, a channel-shaped guide rail with a C-shaped cross section is mounted on a pair of guides 13, 13 with a C-shaped cross section fixed to the stand 4 so as to be slidable in directions a and b. frame 14,14 as
On the other hand, a movable frame 16 which can move forward and backward as shown in A and B through rollers 15, 15, . . . is integrated with bone frames 17, 17, .
8. A reversible drive motor 2 is mounted on a bracket 20 provided at the rear of the roller 19 and supporting the driven roll 19 freely.
1 is integrally equipped.

A belt conveyor 11 is stretched between the driving roll 18 and the driven roll 19.
pulley 22 and the reversible type drive motor 21
A belt 24 is stretched between the pulley 23 and the pulley 23, as shown in FIG.

Although the rear ends of the drive motor 21 and the belt conveyor 11 in FIG. 3 appear narrow due to the illustration, there is sufficient space so that they do not interfere in any way with the fall and transfer of the products 5.

As shown in FIGS. 1 and 2, a discharge pallet 26 for the runner 6 is installed at the tip of the belt conveyor 11 via a plate-shaped chute 25, and a bracket 26 is installed on the frame 14 at the rear end.
A chute 29 of a belt conveyor type disposed diagonally through 7 and 28 is provided to transfer the products 5 to a discharge pallet 30.

In FIG. 4, reference numeral 31 designates an advancing/retracting handle for the frame 14, and 32 represents an advancing/retracting handle for the movable frame 16.

In the above configuration, when the injection molding apparatus 2 is installed based on a predetermined design, the frame 14 is pulled out sufficiently forward in the b direction with respect to the guide 13 via the handle 31, and the movable frame 16 is further pulled out via the handle 32. is sufficiently pulled forward in the B direction with respect to the frame 14 to extend it to two stages, set in an operating state, and connect the chute 25 and the chute conveyor 29 to the pallets 26 and 30.

Therefore, when the injection molding apparatus 2 is operated, the take-out machine 7 takes out the products 5 and the runners 6 alternately at set time intervals via a control device (not shown), and transfers and drops them onto the belt conveyor 11.

Thus, the reversible drive motor 21 rotates the drive roll 18 in the forward and reverse directions after a predetermined time lag, rotates the belt conveyor 11 in the forward and reverse directions, and the product 5 falls onto the chute conveyor 29 from between the frames 14 and 14. and further transferred and stored on the pallet 30, while
The runner 6 is advanced and transferred and stored on a pallet 26 via a chute 25.

Therefore, the products 5 and the runners 6 are sorted by the belt conveyor 11 which operates synchronously with the take-out machine 7 and are transferred to the respective discharge pallets 30, 26.

Therefore, sorting work as post-processing becomes unnecessary.

When replacing the injection molding device 2 due to setup changes, etc., use the handle 32 to push the movable frame 16 sufficiently backwards in the direction of arrow A against the frame 14 to slide it back to create a space. To prevent mutual interference when changing the setup of the two.

However, if only the retraction of the belt conveyor 11 is required to provide support for the setup change work, the frame 14 is also moved back in the direction of arrow a with respect to the guide 13 via the handle 31 to create a sufficient space and allow the setup change to be carried out smoothly. do the work.

The retraction and reduction of the belt conveyor 11 can also be applied to maintenance and inspection of the injection molding apparatus 2.

Incidentally, it goes without saying that the embodiment of this invention is not limited to the above-mentioned embodiment, and for example, frame 1
4. The movable frame 16 is provided with multi-stage stoppers, so that it can be expanded and contracted in stages instead of a full stroke.
Various modes can be adopted, such as replacing the manual type with an automatic telescoping type.

In addition, the target is not limited to injection molding equipment and runners.
Of course, it is also applicable to other molded products, scraps, etc.

<Effects of the invention> According to this invention, the pair of frames of the main body of the conveyor are used as guide rails, and the movable frame of the conveyor can move forward and backward with respect to the frames via rollers. As a result, not only is there no support for the normal operation of the belt conveyor, but when changing setups or performing maintenance inspections on the forming equipment attached to the conveyor, the belt conveyor must be moved back along with its frame to create a free space that does not hinder work. The molding device can be expanded sufficiently, which has the excellent effect of making it possible to work efficiently without causing damage when replacing the molding device.

In addition, since a reversible drive motor is integrally provided to the movable frame, it can move forward and backward as one unit, so there is no need to engage or disconnect the drive system when moving the belt conveyor back and forth. It has excellent effects.

Furthermore, by operating the drive motor in forward and reverse directions, it is possible to automatically sort and carry out products and accessories such as runners on the belt conveyor to the corresponding carry-out pallets.
Therefore, products and accessories do not coexist on the same conveyance path, and as a result, problems such as damage to products and a reduction in the collection rate of accessories can be avoided.
