Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a bread slicing device for slicing bread to a predetermined thickness.

[Conventional technology]

Conventionally, bread that is sliced to a predetermined thickness and packaged is sold at a bread factory or bakery store, but since the sliced bread is of a predetermined thickness, customers can slice it to the desired thickness. Often, the bread cannot be sliced to the desired thickness.

Therefore, in order to meet this demand, some stores have installed slicing machines in their stores and can slice products right in front of customers according to their wishes.

[Problem to be solved by the invention]

However, as shown in FIG. 8, the conventional slicing device slices the bread by placing the bread on a placing table 51 and moving the placing table 51 back and forth toward the slicing blade 52 while holding the bread with one hand. Since this is done by catching the sliced bread with the other hand, some customers may dislike it for hygiene reasons as the staff will be touching the bread directly with their hands.

For this reason, it would be advantageous if customers could slice the bread themselves according to their preferences.
Although a conventional slicing device is provided with a protective cover 53 around a part of the slicing blade, the slicing blade is exposed in the slicing section where bread is sliced, making it difficult for visitors who are inexperienced to operate it by themselves. This poses a high risk of injury to fingers, etc.

An object of the present invention is to solve the above-mentioned conventional problems and provide a bread slicing device that allows customers to safely slice bread to their desired thickness.

[Means for solving problems]

This invention provides a bread platform that is vertically movably supported on a pedestal, a vertical drive device that moves the bread platform up and down, a knife that has a blade that moves along the slicing surface of bread, and the knife and the bread platform. A cutter rest that supports a device that drives a cutter; a back-and-forth drive device that moves the cutter rest back and forth toward the bread holder; a safety cover that is pivotally mounted to the stand so as to be tiltable up and down; a presser member that is vertically movably supported and capable of holding the bread on the bread platform when closed;
A selection switch that selects the slice thickness, and a control device that controls the drive time of the vertical drive device in response to a signal from the selection switch and moves the bread platform up to the selected slice thickness. With the bread placed on the bread stand being held down by the pressing member provided on the cover, the drive device moves the bread to the thickness specified by the selection switch that selects the slice thickness. The bread is raised, and each time the bread rises, the blade supporting the blade is moved forward and backward toward the bread mounting table, thereby slicing the bread with the blade.
The bread after slicing is arranged so that the sliced bread comes out on a bread platform in the same way as the bread before the start of slicing, without being separated one by one and all stacked on top of each other. In this device, the bread and cutlery are covered by a cover so that the slicing operation can only be performed when hands are kept away from the bread.

[Effect]

According to this invention, when a customer opens the cover and places bread on the bread stand, and closes the cover, the pressing member presses the bread against the bread stand. The bread table with the bread on it is first lowered by the cutter to the lowest position where the top of the bread is below the slicing surface, and when the customer selects and instructs the slice thickness using the selection switch, In response to the signal, a control device that controls the intermittent drive time of the drive device operates using a timer, and the bread platform is raised by the drive device until the slice surface reaches the selected thickness position, and then stopped. Then,
The blade is driven by a slicing instruction to start slicing, and after the bread platform stops, the blade advances, slices the first piece of bread, and then stops. Next, after the bread platform rises to a predetermined height and stops, the tool rest moves backward to perform the second slice.

Thereafter, the process is repeated until a predetermined number of slices have been sliced.

When slicing is complete, open the cover and remove the sliced bread.

Customers simply put in and take out bread with the cover open, and slicing is done automatically with the cover closed.

〔Example〕

The details of this invention will be explained in detail based on the embodiments shown in the drawings.

In FIGS. 1 and 2, the bread slicing device has a bread mount 3 that is vertically guided by a guide rod 2 fixed to a pedestal 1. As shown in FIG.

The bread platform 3 is moved up and down by a vertical drive device 4.

In the illustrated example, the vertical drive device 4 includes a motor 5, a drive pulley 6 that is rotationally driven by the motor 5, a driven pulley 7 that is rotatably supported, and a timing when the drive pulley 6 and the driven pulley 7 are spanned. The timing belt 8 is fixed to the bread platform 3 by a fixture 9. motor 5
The amount of rotation is controlled by the control device 26, and the amount of movement of the timing belt 8 is controlled.
The bread platform 3 can be raised to a desired height and lowered to a standby position. The control device is provided integrally with a selection switch for selecting the slice thickness,
The timer controls the intermittent driving time of the driving device by selecting the selection switch. The driving device is not limited to this example, and any device such as a gear device, a fluid pressure cylinder device, etc. that can move the bread platform 3 intermittently over a predetermined length may be used.

The upper surface of the pedestal 1 is formed into an upper table shape, and the transparent safety cover 10 is attached by a pivot member 11.
It is pivoted so that it can be tilted up and down. safety cover 10
A slit 12 is formed in the slit 12, and a bread holder 13 is supported by the safety cover 10 so as to be movable along the slit 12. Slit 12 is safety cover 10
In the closed state, the bread presser foot 13 is formed to be able to descend almost vertically under its own weight.

A cutter 14 is supported on a tool rest 15, with a substantially horizontal slicing surface A located slightly below the upper table cover of the gantry 1. In the illustrated example, the blade 14 is mounted on a tool rest 15 as an endless belt-shaped blade wrapped around a driving wheel 16 and a driven wheel 17 that are rotatably supported. The drive wheel 16 is rotationally driven by a blade drive motor 18. In addition to the belt-like blade, the blade 14 can also be a disc-shaped blade or a linear blade that reciprocates.

The tool rest 15 is supported by a guide roller 19 so as to be able to reciprocate toward the bread platform 3, and is moved back and forth by a back and forth drive device 20.

In the illustrated example, the longitudinal drive device 20 includes a longitudinal motor 21 supported by the frame 1 and a longitudinal motor 2.
1, and a nut 23 screwed onto the screw shaft 22 and fixed to the tool post 15. The longitudinal drive device can also be formed by a gear device, a hydraulic cylinder, etc.

The operation of this device will be explained below.

As shown in FIG.
The safety cover 1 stops when it is one step lower than the top level and 1 to 2 cm lower than the upper table cover.
0 is closed, the bread holding member 13 is at the lowest position due to its own weight, and the tool rest 15 is at the forward end or reverse end position,
Each drive device is stopped and waiting.

A customer takes out a loaf of bread in a bag from the store's display case, or takes out a bag of bread handed to him at the store, opens the safety cover 10 and removes the bag, as shown in Figure 3. One loaf of bread 24 taken out is placed on the bread stand 3. It is convenient to provide a safety switch or the like so that each drive device does not operate while the safety cover 10 is open.

When the safety cover 10 is closed, the bread holding member 13 automatically rests on the bread 24, as shown in FIG.

Next, change the number of slices, for example, 4, 6, etc.
7 sheets, 8 sheets, 12 sheets, etc. can be selected and commanded using the selection switch 25 as appropriate.

When a drive button (not shown) is pressed, the motor 5 is activated and the bread platform 3 is lowered to the lowest position.
At this time, as shown in FIG.
3 descends together with the bread 24 due to its own weight while remaining on top of the bread 24. Next, the bread platform 3 rises by the selected thickness and stops, and the blade drive motor 18 is driven to drive the blade 14. Then, the forward and backward movement motor 21 is driven, and the blade 15 moves forward. Alternatively, the knife 14 is moved backward and cuts the first slice of the upper end of the bread 24. Since the bread 24 is held down by the bread holding member 13 during slicing, it is avoided that the bread rises and is sliced diagonally. When slicing is completed, the turret 15 is stopped, the motor 5 is activated, the bread platform 3 is raised again by the selected thickness, and then stopped.

Thereafter, the tool rest 15 moves backward or forward in the same manner as described above to perform the second slice.

Thereafter, the above operation is repeated until a predetermined number of slices are completed. When the selected number of slices have been sliced, as shown in FIG. 6, the bread platform 3 rises to the top level, and the end of slicing is notified using the display or voice. Since the bread platform 3 is located above the upper table cover, sliced bread can be easily taken out.

It is more convenient in terms of hygiene if the customer opens the safety cover 10, covers the pile of sliced bread with a bag, and takes the bread out.

When the sliced bread is taken out and the safety cover 10 is closed, the bread platform 3 is lowered one step and stands by in the state shown in FIG.

〔effect〕

According to the present invention, a slicing device which is preferable in terms of hygiene can be obtained, since ordinary customers can very easily and safely slice bread to a desired thickness without touching it with other people's hands. Customers can now slice the bread immediately after purchasing it, making it possible to maintain the freshness of the bread.

If a belt-shaped knife is used as the knife, the distance traveled by the turret can be reduced and the bread can be sliced reliably.Furthermore, the bread is held down by the holding member provided on the safety cover during slicing, so that the bread can be sliced evenly after the bread is cut off. can also be kept in its original shape.

When placing bread on the slicing device or taking it out, you can remove only the bag from the bread, or place the bag over the bread and take out the sliced bread.You can do this without using special tools such as gloves. Since the work can be carried out without having to touch the surface directly, excellent hygienic effects can be obtained.
