Abstract

PURPOSE:To automatize the captioned device without making it large-size by rotating a movable frame after allowing it to pass through a first work on a conveyance path, to switch the path to a second work path, and then opening the first work path, and further repeating these operations alternately. CONSTITUTION:An R member placed on a belt conveyer passes through a fixed frame 4, a movable frame 5, and a stopper 6, and falls onto a chute 7. Thereupon, a photoelectric switch 16 detects the R member and enters the signal into a controller 17. The controller 17 actuates a cylinder 12 to lift the stopper 6 for stopping an L member, and in succession actuates a cylinder 8 to permit the movable frame 5 to decline for allowing the L member to fall onto a chute 15. Then, the cylinders 12, 8 are restored to return to the side of allowing the R member to pass. These operations are alternately repeated. Such arrangement automatizes the captioned device with a simplified and miniaturized structure.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is characterized in that when performing processing such as pressing, two types of workpieces that have been subjected to different processing processes are alternately transferred on a belt conveyor. Moreover, the gevcr 41 is used to sort and align the workpieces at the discharge end.

Conventional technology Generally speaking, in the transfer press method, etc., there are nine workpieces that are press-processed. However, if the workpieces are a pair of products, such as left and right parts that form an article, and they are all transferred alternately on the belt conveyor. may be done. In order to sort these two types of workpieces at the discharge end of the belt conveyor, a method is usually adopted in which a dedicated worker is asked to manually separate and align the workpieces. On the other hand, mechanical means have been considered to separate the pairs of products that are transferred alternately, but in either case, the installation itself becomes large and expensive, and it is difficult to use all of the multi-food products. At present, we rely on manual separation and alignment methods that are difficult to deal with.

Problems to be Solved by the Invention However, with such conventional IT, a full-time worker must be on hand at all times, and the processing speed of the transfer press, If? When raising the product, there is a problem in having the worker continue manual work for a long time, and the product must be transported, so there is inevitably a limit to processing capacity. Therefore, automation of the above-mentioned work is desired, and the present invention aims to deal with the above-mentioned problem.
The purpose of this invention is to provide a device that automatically sorts and aligns workpieces without increasing the size and price of the device.

Means for Solving the Problems The present invention is intended to achieve the above objects, as described above.
In a device that alternately transports all workpieces of mm length on a belt conveyor and sorts and aligns them all at the discharge end, there is a conveyance path through which the first workpiece passes, and A chute mechanism of Maki 1 that arranges and accommodates the workpieces,
a sensor that detects that the workpiece fX1 has passed on the conveyance path; and a stopper that completely stops the passage of the subsequent second workpiece at an intermediate part of the conveyance path in response to the activation of the sensor vc. , a dropping mechanism and a second chute mechanism that drop the stopped second workpieces downward and accommodate them in alignment, and after the IE2 workpieces have fallen, they are moved again onto the conveyor rack to the subsequent first workpieces. It is equipped with a reciprocating mechanism that allows objects to pass through, and by means of the above-mentioned sag, it is possible to transport 24 kinds of workpieces alternately on a belt conveyor, The first workpiece is shot into the chute mechanism of the filler 1 to be lined up and stored, and a sensor detects the passage of the first workpiece, and a stopper is activated in the middle of the conveyance path to load the first workpiece. The entire operation of completely stopping the passage of the workpieces in the second chute, and then operating the dropping mechanism to drop the workpieces in the second chute down the conveyance path, and chute them into the second chute mechanism to arrange and accommodate them. Racho Monoderoru 0 Examples Below Examples of the present invention? A detailed explanation will be given based on the description of the drawings. 1. Figure 1 is a schematic diagram showing the entire FE# of the present invention, and 1 of 1 shows a belt conveyor. M-processed workpieces 2a, 2b, 2c.
If the workpiece to be transferred in sequence is, for example, a vehicle door or roof member, there will be a member (R member) to be loaded on the right side of one car and a member (R member) to be installed on the left side of the car. It has a symmetrical shape with the L member), and if it is the illustrated 2aiR member, 2b has 5 members, and 8 members and 5 members are transferred alternately in the same manner. The discharge end of the belt conveyor 1 is equipped with a sorting and alignment device supported by a frame 3. That is, fixed frame 4. Moving frame 5. A conveyance path is formed by the stopper 6, and the first workpieces that have passed through this conveyance path are aligned and stored in the first chute 7. The movable frame 5 is connected to the tip of a rod 9 protruding from a cylinder 8 fixed to the frame body 3, and is extendable and retractable as shown by arrow A. The stopper 6 is supported by a support shaft 10 and has a rod 1 projecting from a cylinder 12 fixed on a base plate 11 similarly fixed to the frame 3.
A substantially middle portion of the stopper 6 is rotatably connected to the tip of the stopper 3, so that the stopper 6 can be moved up and down as shown by arrow B. Further, a sloped portion 14 extending diagonally downward from the tip of the fixed frame 4 is provided, and a second chute 15 is attached to the lower end of this sloped portion 14. Further, a light switch 16 is provided as a sensor near the tip of the fixed frame 4, and a controller is provided (not shown) for receiving a signal from the photoelectric switch 16 and controlling the operation of the cylinders 8 and 12.

The operation mode of the apparatus of the present invention will be explained below using FIGS. That is, in FIG. 2, the fR member and the 5 member on the belt conveyor 1 are transferred alternately,
Under the condition shown in the figure, the 8 members are the fixed frame 4. Moving frame 5. Stotsuba 6? It falls into the first chute 7 and comes to rest. At this time, the photoelectric switch 16 detects the passage of the eight members and transmits it to the controller 17. Then, the controller 17 first extends the rod 13 of the cylinder 12, so that the stopper 6 rises as shown in FIG. 3 and stops the passage of the five members. Subsequently, the controller 17 shortens the rod 9 of the cylinder 8 to cause the five members stopped on the moving frame 5 to fall toward the slope portion 14 as shown in FIG. Let the member fall and stand still. Subsequently, the controller 17 again controls the cylinder 12. 1 is actuated to lower the stopper 6f as shown in FIG. 5, extend the moving frame 5, and allow the following eight members to pass through the first chute 7 in the same manner as shown in FIG. .

If a control system with a built-in timer is used as the controller 17, for example, after the photoelectric switch 16 is turned on, the stopper 6 and the moving frame 5 are actuated by the cylinders 12 and 8, respectively, for a predetermined period of time, and only one L member f is used. As explained above, according to the device of the present invention, it is possible to perform sequence control such as dropping the illumination to the second chute 15 side and returning it to the original state again. All of the R members that are the workpieces can be arranged and stored, and the five members that are the second workpieces can be automatically stored in the second chute 15 located at the lower stage. Once a predetermined number of workpieces are stored in each chute, the work can be continued by transporting these workpieces to the next process using other conveyance means.0 Effects of the Invention and More By applying the invention described in detail, the following advantages can be brought about.

That is, in a work situation such as a transfer press where workpieces are sequentially transferred on a belt conveyor, when products such as the above-mentioned 8 members and 5 members are transferred sequentially as bare, the discharge end of the belt conveyor Since the manual work of the operator can be completely eliminated, the effect of labor saving is large. In addition, since the transfer speed of the product can be adjusted appropriately, even if the stroke number (SPM) of a press machine or the like increases, there is no problem with the work, and it can contribute to improving the efficiency of the work.

The shape of the workpiece applied to the present invention is not particularly limited; for example, a shoe for classifying and organizing products). It can be applied to a wide variety of workpieces by being replaced, and the equipment itself has a relatively simple structure, so the manufacturing cost is low and the equipment is economical. Moreover, the device according to the present invention has the advantage that it can be applied to other industrial fields and has great utility value.
