Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product sampling apparatus. 2. Description of the Related Art Generally, in order to determine the quality of a produced product, a sample is taken from the product and inspected. Such samples are withdrawn by the operator at regular intervals and delivered to the inspection department. [0003] However, in such a sampling procedure, the operator must be always on standby, and the work is restricted. For this reason, the container for storing the product, the container body, a lid capable of opening and closing the upper surface opening of the container body, and detachably attached to the input port formed in the lid, and fixing the holding member, When the product is supplied, the grasping member is grasped and the small lid is detached from the input port formed in the lid, and then the product is supplied from the input port. On the other hand, when a set number of products are supplied, a sample collection device is proposed in which a small lid is attached to the input port of the lid and a product sample is supplied to a storage recess formed in the small lid. (See Japanese Patent Application Laid-Open No. 5-72082). [0004] In the above-described sample collecting apparatus, when a product sample is supplied to a storage recess formed in a small lid, the product collides with a holding member and cannot be stored smoothly. There was a problem. Further, since the gripping member must be attached to the small lid, the cost is increased, and the small lid cannot be stacked and stored. Further, such a sampling device is
Although it is installed near the dispensing device that stores the product storage container, there is also a problem that it cannot be adopted if the installation space cannot be secured. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a product sample that can be smoothly placed in a storage recess and that can be installed using the dead space of a dispensing device. A sampling device is provided. According to the present invention, there is provided a lifting device provided on a fixed frame sandwiched between left and right storage containers stacked in a plurality of stages, and a lifting device connected to the lifting device, and It consists of a chuck device having a pair of chucks that can be approached or separated, and by operating the chuck device, the inner surface of the storage recess of the small lid attached to the input port formed in the lid of the storage container or the lid of the storage container A pair of chucks are held in close contact with the inner surface of the formed storage recess, and the small lid or the lid is attached and detached by operating the elevating device while holding the small lid or the lid by the chuck. Things. When the container for the product is carried in, the pair of chucks of the chuck device are lowered into the storage recess of the small lid via the elevating device, and then the pair of chucks are reduced via the chuck device. The lid is in close contact with the inner surface of the storage recess. Next, the small lid held by the pair of chucks is lifted through the lifting device,
The opening formed in the lid is opened. Thereafter, the container is unloaded and a set number of products are supplied through the inlet. When the supply of the product is completed, the container into which the product has been supplied is carried in, and a small lid is attached to the input port of the lid via the elevating device. The chuck device is removed from the lid, and the chuck device is retracted above the small lid via the lifting device. Next, the storage container is unloaded, and a product sample is supplied to the storage recess of the small lid. [0010] Instead of forming the storage recess in the small lid, a storage recess may be formed in a part or the whole of the lid to store a product sample. As a result, a product sample can be automatically collected in association with the product storage container.
Since the small lid or the lid body is tightly held by the pair of chucks on the inner surface of the storage recess, the supply of the product is not hindered, and the product sample can be smoothly stored in the storage recess. . Further, since the space is provided using the space between the storage containers stored in the dispensing device, a new installation space is not required.

Then, when the container 4 reaches the position facing the chuck device 3, that is, the pair of chucks 36 of the chuck device 3 reach the position directly above the input port 42a formed in the lid 42 of the container 4, The driving of the chain conveyor 53 is stopped. Here, when the air cylinder 22 is extended, the rotation of the chuck device 3 is restricted by the rotation preventing rod 23 and the chuck device 3 descends. Then, when the air cylinder 22 reaches the stroke end, the pair of chucks 36 of the chuck device 3 are positioned in the storage recess of the small lid 43 (see FIG. 2). Thereafter, when the air cylinder 33 is extended, one chuck 36 to which the piston rod is connected advances. At this time, a pair of guide rods 35 slidably fitted to the slide bearings 34 are connected to one of the chucks 36, so that the chucks 36 are restricted by the guide rods 35 and move forward without bias. When one chuck 36 advances, the lever 38 is rotated counterclockwise with respect to the pin 31A via a rod 39 connected to the chuck 36, and the other chuck 36 is rotated via a rod 39 connected to the other end. Is pushed out together with the guide rod 35 inserted into the slide bearing 34, the pair of chucks 36, 36 move in the direction away from each other, and the contact pieces 36a, 36a Adhere to When the small lid 43 is held in close contact with the chuck 36, the air cylinder 22 is contracted and the chuck device 3 is raised.

As a result, the lever 38 is rotated clockwise via the rod 39 connected to the pulled-back chuck 36, and the other chuck 36 is pulled back via the rod 39. Therefore, a pair of chucks 36,
36 move in a direction approaching each other, and detach the contact pieces 36 a of the pair of chucks 36 from the inner peripheral surface of the concave portion of the small lid 43. Thereafter, the air cylinder 22 is again contracted to raise the chuck device 3. Then, the chain conveyor 53 is driven again, and the container 4 with the small lid 43 attached thereto and supplied with the product is transported to a supply position facing the chute 54, and the leading end of the chute 54 communicates with the input port 42 a. Thereafter, the molded product is supplied from the molding machine for one shot or a plurality of shots, so that the molded product is stored in the storage recess of the small lid 43 via the chute 54. The molded product stored in the storage recess of the small lid 43 becomes a sample of the molded product that has been formed and supplied to the storage container 4 up to that time. At this time, there is no obstacle in the supply of the molded product to the storage recess of the small lid 43, and the molded product can be stored smoothly. When the supply of the sample is completed, the chain conveyor 53 is driven, and the container 4 is transported to an appropriate storage location, or is transported to a receiving position immediately below the other group of containers 4 and the lifting support device is moved. Through the lowermost container. Then, these containers 4 are finally sent to the inspection department, and the quality of the molded article supplied to the containers 4 is estimated by inspecting the samples stored in the storage recesses of the small lid 43. Can be. In this case, the sample is previously taken out of the container 4 in association with the container 4, and the operation of removing the lid 41 and collecting the sample becomes unnecessary. In addition, there is no problem even if the storage containers 4 are stacked, and it is not necessary to perform special handling. On the other hand, when the container 4 containing the set number of molded articles is carried out or collected, a new container 4 is stored.
