Description

[Detailed description of the invention] Industrial application field This invention is based on, for example, a rotating round blade that is installed upright on one side of the machine base, and a machine that is loaded while reciprocating with its front end along the rotating surface of the round blade. The present invention relates to a lower conveyor of a meat slicer, which is attached to the bottom of the meat box of the meat slicer and is used for sending out the material.

BACKGROUND ART The bottom of a meat box is formed to facilitate cleaning before and after use of a meat slicer, and to facilitate operations to remove slack in the conveyor belt for feeding materials that occurs during use. For example, in the lower conveyor of a meat slicer, a conveyor frame with a conveyor belt stretched inside the frame is removably attached so that the conveyor belt can be taken out of the machine with the conveyor belt stretched. Showa 60-
In addition to No. 33718 (Japanese Utility Model Publication No. 61-151892), there is also a material feeding device for a meat slicer disclosed in Japanese Patent Application Laid-Open No. 57-151515.

Problems to be Solved by the Invention The former of the above-mentioned conventional devices has two mounting shafts, one for the front and one for mounting the lower conveyor inside the frame of the meat box, to be taken out of the machine and a support for the rear end of the belt conveyor. The rear wheel bearing, that is, the rear bearing, swings around the pivot shaft, which loosens the tension on the belt conveyor, which has the advantage that the belt conveyor can be easily attached to and detached from the conveyor frame. The operation of moving the position of the rear bearing to eliminate slack in the conveyor belt and re-tensioning it is done by expanding and contracting the bolts and nuts that are located on the back side of the endless conveyor belt and are interposed between the rear bearing and the pivot shaft. This must be done by operation, so
It was necessary to repeat the rocking and repositioning of the rear bearing several times before proper adjustment, and there was a drawback that the tension of the conveyor belt could not be adjusted while it was still attached to the conveyor frame. On the other hand, in the latter case, the support shaft of the rear wheel is fixed to the tips of two support rods that are slidably placed horizontally along both inside sides of the conveyor frame, and the support rods are always biased toward the rear. In addition to providing a spring for tensioning the conveyor belt, the conveyor frame is also provided with a long hole provided in the conveyor frame and a set screw pin that fits into the long hole and is attached to the two support rods. - The conveyor belt is configured so that the tension can be adjusted while it is still tensioned on the frame, but the conveyor belt can be attached or detached by pushing the rear wheel support shaft back inward against the tension of the tension spring. Because it requires a conveyor belt, it has the disadvantage that it is less easy to attach and detach compared to the former, and each has its own advantages and disadvantages, so it has been desired to improve the conveyor belt so that it can be easily attached and detached as well as the tension adjustment.

Means to Solve the Problems Therefore, the present invention has developed a conveyor frame that is removably fitted into the frame that forms the bottom of the meat box.
At the rear of the conveyor frame, a driving shaft is removably connected to the material feeding drive shaft attached to the frame and supports the front end of the material feeding conveyor belt and rotates integrally therewith. A rear bearing is provided that allows the mounting position to be moved along the length of the frame by connecting with a long hole provided along the length of the frame and a screw pin that fits into the long hole. A rear wheel that supports the rear end of the conveyor belt is attached to a support shaft provided on the rear bearing, and the conveyor belt is tightened by tightening the screw pin from the outside at the position where it fits into the elongated hole. In a lower conveyor of a meat slicer that is maintained in a stretched state, a spring for tensioning the conveyor belt is provided, one end of which is hooked to the screw pin and the other end of the conveyor belt is hooked to the conveyor frame. ,
There is provided a lower conveyor for a meat slicer, characterized in that the base of the rear bearing is loosely fitted to the screw pin so that it can swing around the screw pin as a fulcrum. .

Function The lower conveyor of the present invention configured as described above is
After removing the conveyor frame from the frame of the meat box with the conveyor belt still in tension, loosen the tightening of the screw pin, the rear bearing will swing together with the rear wheel using the pin as a fulcrum, so the conveyor The belt can be easily attached and detached, and by restoring the rear bearing, the appropriate tension is applied to the conveyor belt by the action of the tensioning spring, and by tightening the screw pin at the balanced position, the conveyor belt can be tightened. Since re-tensioning and tensioning adjustment can be completed at the same time, the above-mentioned drawbacks of the conventional method can be solved.

Embodiments Examples of the present invention will be described below with reference to the drawings.

C is a blind-type material feeding conveyor belt whose front end C' is supported via sprockets 2a and 2b at both ends of the drive shaft 1 and rotates integrally with the drive shaft 1 (counterclockwise in Fig. 2); 3 is a conveyor frame; - A pair of left and right rear bearings provided at the rear of the vehicle F. This rear bearing 3 is fitted into a long hole 4 provided along the length of the conveyor frame F, and fixed in its fitted position by tightening a female screw 5' from the outside. By connecting the base 3' to the screw pin 5, which is attached to the screw pin 5, the mounting position can be moved in the longitudinal direction, and the base 3' is loosely fitted to the inner end of the screw pin 5. and the screw pin 5
It is provided so that it can swing around the fulcrum.
A support shaft 6 is fixed to the rear bearing 3 and has rear wheels 7 of a lower conveyor rotatably attached to both ends thereof.
The conveyor belt C has its rear end C'' connected to the rear wheel 7.
The tensioned state is maintained by being supported by. 8
