[Prior Art] Conventionally, an apparatus for automatically wrapping a product in which foods and the like are packed in a pallet with a resin film has been used in various food industries in consideration of workability and hygiene.

[Problems to be solved by the invention] However, in many cases, since products flow in a line, it was necessary to manually set the lapping devices one by one in order to supply the products.

It is an object of the present invention to provide an intermittent feeding device that can intermittently feed one by one when lapping products that are successively conveyed, for example.

[Means for Solving the Problems] In the intermittent feeding device according to the present invention, products are continuously fed in the device for intermittently feeding the product on the first feeding conveyor onto the second feeding conveyor. First to make the still
A first stopper mechanism installed in the vicinity of the terminal end of the feeding conveyor, and a second product for stopping a succeeding product before the first stopper mechanism when the first product released from the stationary state by the first stopper mechanism is delivered. A stopper mechanism, a conveyer conveys the product whose rest has been released by the first stopper mechanism to the starting end of the second feed conveyor, and the operation of the first stopper mechanism and the second stopper mechanism of the second feed conveyor. And a stopper actuation mechanism for controlling according to the product transport distance.

In one embodiment disclosed in the present invention, the second feeding conveyor is a conveyor that hooks and feeds a product by the movement of a feeding finger protruding on the conveyance surface.

Further, the first stopper mechanism has an L-shaped substrate having one side that slides in a direction orthogonal to the transport direction, a cam mechanism installed on the one side, and a cam mechanism that moves in and out on a transport surface. And a sliding shaft that makes the first product stand still.

Further, the second stopper mechanism is composed of an L-shaped stationary shaft that is erected on the other side edge of the substrate that comes in and out in the side direction of the second product and stops the second product. There is.

Further, the stopper actuating mechanism is connected to the substrate as a stopper actuating arm by connecting a transmission portion obliquely passed in a feeding direction of the feeding finger, a supporting portion pivotally supported by an upstanding support shaft, and the substrate. And the pressing mechanism that presses in the direction orthogonal to the transport direction of the substrate.

[Operation] In the present invention, the first stopper mechanism is provided near the end of the first feeding conveyor to stop the products fed continuously, and the stationary state is released by the first stopper mechanism. At the time of delivering the first product, a second stopper mechanism for stopping the succeeding product in front of the first stopper mechanism and a product released from the stillness by the first stopper mechanism are conveyed to the start end of the second feeding conveyor. Since the conveyor is provided with a stopper actuating mechanism for controlling the operation of the first stopper mechanism and the second stopper mechanism according to the product conveying distance of the second feeding conveyor, products successively conveyed. Can be intermittently sent to the second feeding conveyor one by one, and since the second stopper mechanism is provided, the stationary operation of the first stopper mechanism is obstructed by the subsequent product. There is no possibility that two products will be sent out in succession.

[Embodiment] FIG. 1 is a perspective view showing the construction of an embodiment of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a front view showing the operation of the first stopper mechanism of FIG. Is.

In the figure, the intermittent feeding device 0 of the present invention is installed from the terminal end of the first feeding conveyor 7 to the starting end of the second feeding conveyor 3.

In the second feeding conveyor 3, the feeding fingers 31 projecting and moving on the conveying plate surface 32 catch the product 9 and slide the product on the conveying plate surface 32 to feed the product 9.

At the end of the first feeding conveyor 7, there is a first stopper mechanism 1 that makes a set of sliding shafts 11 project on a conveying surface 71 of the first feeding conveyor 7 so that the product 9 stands still. The first feeding conveyor 7 is constantly sliding, the first stopper mechanism 1 stops the progress of the product 9, and the bottom surface of the stopped product 9 slides on the transport surface 71.

The first stopper mechanism 1 is provided with a set of conveyors 2 for conveying the product 9 that has passed through the first stopper mechanism 1 to the starting end of the second feed conveyor 3. The conveyor 2 is composed of a pair of rubber belts 22 installed on both sides of the second conveyor 3 so that the start end and the end of the second conveyor 3 overlap with each other. The drive of the feeding conveyor 3 is transmitted to the sprockets 33 and 21 via the belt 23.

The interlocking mechanism with the first stopper mechanism 1 is performed by a bent stopper operating arm 4. The stopper actuating arm 4 includes a dog-shaped transmission portion 41 that is obliquely passed in the feeding direction of the feeding finger 31, and a support shaft 45 that is vertically erected.
It is composed of a support portion 42 pivotally supported by the above, and an L-shaped action portion 43 connected to the substrate 6 forming part of the first stopper mechanism 1 and the second stopper mechanism 5.

The substrate 6 is L-shaped having one side 12 that slides in a direction perpendicular to the carrying direction and one side 52 that is parallel to the carrying direction.

The stopper actuating arm 4 is constantly pressed by the spring 44 in the direction opposite to the feeding direction of the feeding finger 31,
Since the feeding finger 31 moves while contacting the transmission portion 41, a force for sliding the substrate 6 connected to the operating portion in a direction orthogonal to the transport direction is transmitted with the support portion 42 as a fulcrum. The operating time of the substrate 6 is determined by the moving speed of the feeding finger 31 and the length of the transmission portion after the feeding finger 31 comes into contact with the product. 1 It takes time to finish passing through the stopper mechanism 1.

The first stopper mechanism 1 includes the L-shaped substrate 6 as described above,
One side 12 that slides in a direction orthogonal to the direction in which the substrate 6 is conveyed.
It is composed of a cam mechanism installed above and a sliding shaft 11 that moves in and out on the conveying surface by the cam mechanism. The cam mechanism includes a slide cam shaft 13 installed obliquely and a slide cam shaft 13 And a holding cylinder 15 for slidably holding the sliding shaft 11. In FIG. 3, when one side 12 of the substrate 6 slides horizontally, the slide cam shaft 13 obliquely installed on the substrate 6 also slides horizontally, and the slide portion 14 moves downward along the slide cam shaft 13. And holding cylinder
The sliding shaft 11 held by 15 slides downward.

The second stopper mechanism 5 is composed of an L-shaped stationary shaft 51 erected on the end of the other side 52 of the substrate 6, and is driven by the slide of the substrate 6 to move in the lateral direction of the product. At the time of feeding / removing a product that is stationary by the sliding shaft 11 (when the sliding shaft 11 is retracted), the next product is stationary. The second stopper mechanism prevents the second product following the first product from being pushed up by the sliding shaft 11 of the first stopper mechanism and the two products from being continuously sent out.

Next, the operation of this device will be described. FIGS. 4a to 4d are top views of the present apparatus over time.

In FIG. 4a, a pair of slide shafts 11 of the first stopper mechanism 1 are projected on the conveying surface 71 of the first feeding conveyor 7 so that the first product 91 is stationary and the feeding fingers 31 are stoppers. It is moving in contact with the transmission part 41 of the operating arm 4. This force is transmitted as a force for sliding the substrate 6 connected to the action portion 43 in a direction perpendicular to the transport direction with the support portion 42 as a fulcrum.

In FIG. 4b, the sliding shaft 11 slides and retracts due to the movement of the slide cam shaft 13, so that the first product 91 moves past the first stopper mechanism 1. At this time, the second stopper mechanism 5
The stationary shaft 51 of the second protrusion 92 projects to make the second product 92 stand still.

In FIG. 4c, after the first product 91 has finished passing through the first stopper mechanism 1, the feeding finger 31 is disengaged from the transmission portion 41 and the spring 44 pressing the stopper operating arm 4 causes the first stopper to move. The sliding shaft 11 of the mechanism 1 projects and the stationary shaft 51 of the second stopper mechanism 5 retracts to return to the standby state shown in FIG. 4a. The first product 91 is transferred to the second by the conveyor 2.
The second product 92 is fed to the starting end of the feeding conveyor 3, and the second product 92 is fed to the ending end of the first feeding conveyor 7.

In FIG. 4d, the second product 92 is stationary due to the protrusion of the sliding shaft 11, and the first product is fed by the conveyor 2.
The product 91 is fed by the next feeding finger 31 of the second feeding conveyor 3. After this, as shown in Figure 4a,
The feeding finger 31 comes into contact with the transmission portion 41 of the stopper operating arm 4.

[Advantages of the Invention] As described above, the present invention provides a first stopper mechanism installed near the end of the first feeding conveyor for stopping the products that are continuously fed, and the first stopper mechanism. The second stopper mechanism for stopping the succeeding product in front of the first stopper mechanism and the second product for releasing the stationary state by the first stopper mechanism when the first product released from the stationary state is delivered. Since it is equipped with a conveyor that conveys to the starting end of the conveyor and a stopper actuating mechanism that controls the operation of the first stopper mechanism and the second stopper mechanism according to the product conveying distance of the second feeding conveyor, they are conveyed one after another. Products can be reliably and intermittently sent to the second feeding conveyor one by one, and since the second stopper mechanism is provided, the stationary operation of the first stopper mechanism is the succeeding product. It is possible to obtain an intermittent feeding device that is not hindered by, or that two products are continuously sent out. Especially in the food industry, it is possible to obtain products with high workability and hygiene. is there.
