Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is installed on the top of a meat box that reciprocates along the blade surface of a round blade so that it can be opened and closed, and in cooperation with a lower conveyor provided at the bottom of the meat box, feeds material from the front end of the meat box. The present invention relates to an upper feed device for a meat slicer.

[0002]

[Prior art]

 An upper feed device for a meat slicer includes, for example, as disclosed in Japanese Utility Model Laid-Open No. 52-49390, an upper presser frame that rotatably supports both ends of an upper carrier and fits into the meat box, and a side surface of the meat box. There is one in which a pair of left and right arms swingably supported by a provided fulcrum shaft are connected by rigid joints, and the angle is fixed to an L shape. In addition, as in Japanese Utility Model Publication No. 58-48079, an arm having a rotary transmission mechanism of an upper feeding device is supported by a fulcrum shaft on a side wall on the other side of the meat box, and the other arm having a fulcrum shaft on a side wall on the front side is supported. A notch is provided in the shaft hole of the base to allow escape from the side with respect to the fulcrum shaft, and the bent portion of the L-shaped fixed arm is pressed against the handle for opening and closing the frame. Some are swingably attached.

[Problems to be solved by the device]

 In the former case of the above conventional device, since the upper presser frame and the pair of left and right arms are connected by the rigid joint in the feed operation state in which the upper feeder is closed in the meat box, the upper presser frame suppresses the material from above. Although the force and the force that the carrier sends out the material are sufficiently retained, when the side wall on the front side of the meat box is opened when loading the material into the meat box, the upper presser frame is pulled up from inside the meat box. The front arm is located in the center of the side of the box and interferes with material loading.Therefore, open the entire upper feed device horizontally and diagonally upward toward the side wall on the other side of the meat box. It costs. Therefore, these operations, which are usually performed while standing on the front side of the meat box, are troublesome for the operator, and the work range is widened and power is required.

On the other hand, in the latter, an arm having a fulcrum shaft is fixed to the side wall on the front side in an L-shape and the upper presser frame is hung in the meat box, so that the L-shaped angle bends in the opening / closing direction. It is liable to occur, and there is a drawback that the rigidity of the upper presser frame for pressing the material and the stability of the contact position between the upper feed carrier and the material tend to be insufficient.

Therefore, when the upper presser frame is pulled up from the meat box and opened, the front arm does not interfere with the loading of the material, and the work and labor at the time of loading the material are reduced, while It is important to maintain the rigidity of the connection between the upper presser frame and the pair of left and right arms connected to both sides of the upper presser frame so that the rigidity for pressing the material and the stability of the upper carrier can be sufficiently maintained. It was a problem to be solved in this kind of device.

[0006]

[Means for Solving the Problems]

 Therefore, in order to solve the above-mentioned problems, the present invention swings on an upper pressing frame that rotatably supports both ends of an upper carrier and fits inside a meat box, and a fulcrum shaft provided on the side surface of the meat box. In the upper feeder of the meat slicer having a pair of left and right arms supported by the arm, one arm that swings along the other side of the meat box with a built-in rotation transmission mechanism is used as a rigid joint. The other arm, which is connected to the upper presser frame and is supported by a fulcrum shaft provided on the front side wall of the meat box, has a notch in the shaft hole that fits with the fulcrum shaft so that it can escape from the fulcrum shaft. The upper presser frame is connected to the upper presser frame by a smooth joint, and a receiver for contacting the arm and maintaining an angle with the upper presser frame is provided on the upper presser frame in the upper feed operating state. It provides an upper feed device for meat slicer .

[0007]

[Action]

 In the present invention, the upper feed device has a fulcrum shaft on the front side surface of the meat box, and when the forearm arm is removed from the fulcrum shaft, the arm connected to the upper presser frame by a joint can be freely rotated. Therefore, it is possible to pull up the upper presser frame from inside the meat box and rotate only this open arm on the front side to place it in the avoidance position so as not to disturb the material loading. Further, when the upper presser frame is fitted into the meat box and the upper feed device is closed in the feeding operation state, the front side arm comes into contact with the receiving metal fitting provided on the upper presser frame and is brought into contact with the upper frame. The connection angle with the presser frame is fixed. Therefore, despite the fact that the connecting part with the upper presser frame is a joint, a rigid part is formed in the direction in which the angle opens in the same way as the other arm, and the rigidity of the upper presser frame that presses the material and the frame The stability of the upper carrier supported at both ends by the frame is maintained. The present invention has solved the above problems as described above.
