Description

TECHNICAL FIELD The present invention relates to a meat slicer having an automatic thickness adjusting device for automatically moving a pad to a desired position.

2. Description of the Related Art A conventional slicer of this type is disclosed in Japanese Patent Application Laid-Open No. 55-137900, which is a prior application of the present applicant. Further, in a slicer having a releasable detachable plate, a slicer equipped with a safety device for preventing the slicer from being driven when the relieve plate is not attached is also included in the prior application of the applicant. -8474 is available.

The safety device attached to Japanese Utility Model Publication No. 58-8474 has a contact rod which hangs the lower edge of the backing plate and which follows the movement of the contact rod in the front-rear direction. Is provided so as to be slidable by projecting from the front end of the machine base of the slicer, and the presence or absence of the backing plate is detected by the operation of a safety switch provided so as to engage with this detection rod.

Further, the backing plate of the slicer has a gear bearing inside the base of the backing plate, and is integrally provided with the backing plate together with a manually operated shaft that rotates the gear forward and backward, while a rack rod provided with a rack that meshes with the gear. Since the support rod that guides the movement of the backing plate was fixed to the machine side of the slicer, the thickness adjusting device is disassembled when the backing plate is attached and detached, and the backing plate can be attached and removed before and after using the slicer. The attachment of the thickness adjusting device does not hinder it.

However, as in Japanese Patent Laid-Open No. 55-137900, a slicer provided with an automatic thickness adjusting device has a reliable detachable cover plate as shown in FIG. 2 attached to the present invention. A base to be attached, a thickness adjusting shaft fixed to the tip at the tip and slidably provided along the moving direction of the backing plate, and fixed to the front end of the machine base of the slicer,
A body that slidably bears the thickness adjusting shaft, a drive shaft that is connected to a pad plate driving motor installed outside the body, and drives the thickness adjusting shaft via a rotation transmission mechanism inside the body,
It consists of a movement controller for detecting whether or not the backing plate has reached a set position from the rotation of the drive shaft, and like the thickness adjusting device of the above-mentioned Japanese Utility Model Publication No. 58-8474, attaching and detaching the backing plate. Since it is not possible to easily disassemble or combine the thickness adjuster, the backing plate of these slicers was limited to attachment / detachment with the base portion left on the automatic thickness adjuster side integrated with the slicer. .

From the above, the meat slicer equipped with the automatic thickness adjusting device is structurally desired, while it is desired to install a safety device for detecting the presence or absence of the backing plate and controlling the on / off of the drive of the slicer. There was a drawback that it could not be attached.

Therefore, it has been a problem to be solved in this type of slicer to attach a safety device for detecting the presence / absence of a reliable contact plate without largely changing the structure of the slicer with an automatic thickness adjusting device.

Means for Solving the Problems Therefore, according to the present invention, an automatic thickness adjusting device that automatically moves a patch plate that regulates the thickness of a slice piece to a set position is detachably attached to the patch plate via a set screw. A base, a thickness adjusting shaft that is fixed to the tip and is slidable along the movement direction of the backing plate, and a slicer that is fixed to the front end of the machine base and is slidable on the thickness adjusting shaft. For driving a backing plate installed outside the body, by driving the thickness adjusting shaft in the forward and backward direction of the backing plate through a rotary transmission mechanism mounted between the body bearing on In a meat slicer consisting of a drive shaft that is interlocked with a motor and a movement controller that detects whether or not the pad plate has reached a set position from the rotation of the drive shaft, in the joint surface between the base and the pad plate. Put the safety switch facing the detection surface The conductor connected to the safety switch is installed in a recess provided on the base side, and is inserted into a hollow portion formed in the base by communicating with the recess, and the conductor is parallel to the thickness adjusting axis. A meat slicer fixed to a base body, the tip of which is slidably supported in the body, inserted into a hollow support shaft that advances and retreats together with the thickness adjusting shaft, and connected to a drive circuit of the slicer. Is provided.

The pad plate attached to the slicer of the present invention can be attached / detached only to / from the base body integrally fixed to the automatic thickness adjusting device by tightening and loosening the set screw.
Also, the presence or absence of the backing plate is detected to turn on the slicer drive.
The safety switch that is turned off is installed in the recess of the base that is integrally connected to the automatic thickness adjuster with the detection surface facing the contact surface with the backing plate, so the meat slicer with the automatic thickness adjuster is installed. A safety device can be attached to the device, and it is not necessary to hang the contact piece from the base portion of the backing plate as in the safety device of a slicer without a conventional automatic thickness adjusting device.

In addition, the safety switch of the slicer of the present invention has its sensing surface directly covered by the joint surface of the backing plate mounted on the base body, and is protected from water wetting and adhesion of oil and fat. In addition, since the conductor wire connecting the safety switch to the drive circuit of the slicer is inserted into the hollow support shaft provided so as to advance and retreat together with the thickness adjusting shaft from the hollow portion formed in the base body, The automatic thickness adjusting device avoids contact with the body of the automatic thickness adjusting device during movement to prevent damage, and since it does not appear outside the machine stand, it is protected from water wetting and has durability.
