Description

  The present invention relates to a transport take-out apparatus, and more particularly to a transport take-out apparatus that transports a plurality of transported objects in close series.

  As this type of conveying / extracting apparatus, there is conventionally known an apparatus equipped with a so-called clipping device for separating a plurality of continuous conveyed items individually. An example of a transport take-out device using a cutting device is shown in FIG. 4, which shows a state where a transported object is cut out. In the following description, the top of FIG. 4 is the top, the bottom of the figure is the bottom, the right of the figure is the front, and the left of the figure is the back.

  In FIG. 4, the transport take-out device (12) is arranged with a gap at a predetermined position on the upper surface of the conveyor (13) that transports a plurality of transported objects (2) in close series, and moves the transported object (2). A fixed stopper (14) that prevents the movement, an elevating suction head (15) that is arranged following the fixed stopper (14) and moves up and down as indicated by an arrow G, and a front and rear conveyance provided above the conveyor (13) A fixed upper guide (17) that prevents parts of the object (2) from overlapping each other, a fixed side guide (18) for maintaining the in-line state of the conveyed object (2), and a plurality of close-series conveyances It consists of a cutting device (30) for cutting the objects (2) individually.

  The cutting device (30) has a first cutting member (31) that is movable in the vertical direction, and is placed behind the first cutting device (31) with an interval of one transported object (2) and is movable in the vertical direction. And a second cutout member (32). The first cutout member (31) and the second cutout member (32) are moved up and down by a drive device (not shown), and the timing of the vertical movement of both members (31) and (32) is controlled by a control device (not shown). It is controlled by.

The cutting device (30) first lowers the first cutting member (31) to stop the moving tip (21), and then lowers the second cutting member (32) to transfer the tip. A second cutout member (32) is interposed between the object (21) and the subsequent conveyed object (22). When the first cutting member (31) is raised as it is, the transported object (21) at the tip is separated from the subsequent transported object (22) and moved to the fixed stopper (14). Then, when the first cutout member (31) is lowered and the second cutout member (32) is raised, one conveyed product (21) is cut out as shown in FIG. As described above, the cutting device (30) cuts the conveyed product (2) individually by repeatedly raising and lowering the first cutting member (31) and the second cutting member (32). Then, the transported article (21) cut out is sucked and taken out by the lifting / lowering suction head (15).

  The above-described transfer / take-out device is expensive because the cut-out device requires a drive source and a control device, and the occupation area necessary for installation is also increased. For this reason, it is difficult to install the above-described conveyance take-out device in a narrow space.

  An object of the present invention is to provide a transport / take-out device that is inexpensive and can be installed even in a narrow space.

According to the present invention, there is provided a conveying and unloading device, wherein a fixed stopper is disposed at a predetermined position on the upper surface of a conveyor that conveys a plurality of conveyed objects closely in series with each other, and a rear end of the fixed stopper prevents the movement of the conveyed objects. The lifting / lowering suction head arranged in a raised position, the movable upper guide that can be moved back and forth so that the front end portion can be seen below the rear part of the lifting / lowering suction head in the raised position, and the rear of the movable upper guide are spaced apart from each other. It is composed of a fixed upper guide that is arranged, and a lower front inclined surface is formed on the front surface of the movable upper guide, and a contact portion that abuts the inclined surface is provided at the rear lower end of the lifting and lowering adsorption head, The guide is normally urged forward by a push spring provided at the front end of the fixed upper guide, and the lower abutting portion slides on the inclined surface as the elevating suction head descends, and the movable upper guide is moved. The those that have been made to push back far away from the transfer material that is stopped by a fixed stopper against the spring force.
The conveyed product is, for example, a link used in a power transmission chain and having a through hole, but is not limited thereto.
The conveyor may be linear or curved.

  When the transported object is prevented from moving by the fixed stopper, the transported object may be lifted due to an impact generated on the transported object, and a part of the transported objects at the front and back may overlap each other and be unable to be attracted. The fixed upper guide and the movable upper guide prevent the non-adsorbable state, and it is not necessary to hold down the upper surface of the conveyed product at that time, and the fixed upper guide and the movable upper guide may be installed with a slight gap. The slight gap is a gap that does not overlap a part of the transported object before and after, and is appropriately determined according to the thickness of the transported object to be moved.

The lifting / lowering adsorption head may be configured to be able to suck and hold the conveyed product in a vacuum, or to attract and hold the conveyed product by an electromagnet if the conveyed product is a magnetic material. If it is, it is not restricted to these, It is possible to apply a well-known technique.
When the lifting / lowering suction head approaches the transported object stopped by the fixed stopper, the contact portion comes into contact with the inclined surface of the movable upper guide, but since the inclined surface is inclined downward and forward, the lifting / lowering suction head after the contact is While moving down, the movable upper guide is slid rearward until it is away from the conveyed product stopped by the fixed stopper. Therefore, the lifting / lowering suction head can suck the conveyed object stopped by the fixed stopper without being blocked by the movable upper guide. Here, in order to prevent the conveyed object adsorbed when the lifting / lowering suction head is lifted from being caught on the front end portion of the movable upper guide, the length of the lifting / lowering suction head is approximately equal to the length of the front / rear of the conveyed object. The front end of the lifting / lowering suction head does not hit the fixed stopper, and the rear end of the lifting / lowering suction head is such a length that the movable upper guide can be reliably retracted.

  The number of the push springs may be one or two. For example, if a strong biasing force is required, the number may be three. However, the number is not limited to these numbers.

If the biasing force of the push spring is weak, the push spring can be shrunk even if the lifting force of the lifting / lowering suction head is weak. If this is the case, the push spring cannot be contracted. Therefore, in order to prevent the inclined surface of the movable upper guide from being damaged even if it receives a strong force from the lifting / lowering suction head, the contact portion of the lifting / lowering suction head is chamfered to remove corners, or a rolling mechanism such as a roller is attached. It is preferable to use a material having high self-lubricity.
In the transport take-out device according to the present invention, a holding shaft for winding the push spring is fixed to one of the fixed upper guide and the movable upper guide, and the movable upper guide is fixed to the other by a fixed stopper. It is preferable that an insertion hole is provided for inserting the holding shaft when it is pushed back away from the conveyed product.

  If it does in this way, a movable upper guide can move back and forth stably, and a press spring can also be shrunk stably.

  A fixed side guide may be used for the conveyor to maintain the serial state of the conveyed product.

  According to the carrying out and taking out apparatus of the present invention, it is possible to carry out the carrying separately without using a cutting device that requires an expensive drive device or control device, and therefore, the cost can be reduced. Furthermore, since the guide mechanism is smaller than that of the cutting device, the conveying / extracting device according to the present invention can be easily installed even in a narrow place where the setting is difficult when the cutting device is used.

  The present invention will be described below with reference to the drawings.
