Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a plate-like object that is conveyed in a half-stack for the purpose of, for example, packing flat cakes in a half-stack and packing them, or vacuum-packing ham in a half-stack for labeling. The present invention relates to a half-stack conveying device.

[0002]

[Prior art]

 In a certain food industry, flat cakes are stacked in half in a box to make it look good, or multiple vacuum-packed hams are stacked in half so that it can be seen as a service product. Is going to paste. As a device to be used at that time, the confectionery or vacuum-packed ham is conveyed to the second belt conveyor device by the first belt conveyor device, and the confectionery or ham sent next is half-overlapped. As described above, there is one in which the second belt conveyor device is moved intermittently.

[0003]

[Problems to be solved by the device]

 However, depending on the type and shape of the plate-shaped objects, it is difficult to convey them in a half-stack, or even if initially successful, if the moving speed of the second belt conveyor is increased in order to improve the working capacity, the inertia and friction of the plate-shaped objects will increase. Due to force, the half-overlapped state collapsed, and the intended purpose was sometimes not achieved. Therefore, an object of the present invention is to provide a semi-overlap conveying device for plate-like objects which solves the above-mentioned drawbacks.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the plate-like material half-ply conveying device according to the present invention is provided with a first belt conveyor for conveying the plate-like material, and a first belt conveyor which is disposed at the end of the first belt conveyor. A device comprising a second belt conveyor that moves intermittently so that when a plate-like object is sent, the plate-like object is conveyed next and the plate-like object is half overlapped. Use a flexible belt conveyor and place the vacuum chamber directly below the second belt conveyor with the opening facing upward, and at least when the second belt conveyor moves intermittently, connect the vacuum chamber to the vacuum source. It is characterized in that the plate-like material which is half-stacked is sucked. The air permeability of the second belt conveyor need only be such that the vacuum chamber can suck air through the belt conveyor. For example, the second belt conveyor may be formed of a foam material to have air permeability, or the belt may have small holes. A large number may be provided to provide air permeability. When the small holes are formed, they may be formed only in the region where the plate-like objects are lined up in a semi-overlapping state, or may be formed in the entire belt.

[0005]

[Action]

 In the present invention, when the breathable second belt conveyor moves intermittently, the vacuum chamber immediately below the belt conveyor sucks a half-stacked plate-like object, and Also, since the frictional force with the belt conveyor can be increased, most plate-shaped objects can be transported in a half-stack without being affected by the inertia and frictional force of the plate-shaped objects. It is also possible to increase the carrying capacity of the second belt conveyor by increasing the suction force.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the illustrated example, vacuum-packed hams (hereinafter referred to as pack hams) are stacked in three layers and used in the preceding stage of a device for labeling the top and bottom. The basic configuration is such that the pack ham H sent from the first belt conveyor 1 is arranged at the end of the first belt conveyer 1 which conveys the pack ham H one after another, and the pack ham H sent from the first belt conveyer 1 is ¼. It is composed of a second belt conveyor 2 which is staggered and stacked in three stages. The second belt conveyor 2 intermittently moves by 1/4 of the total length of the pack ham when the pack ham H sent from the first belt conveyor 1 is detected by an optical sensor or the like, and this is repeated to point A. When three layers are stacked, the motor is controlled via a motor (not shown) that drives the second belt conveyor 2 so as to rapidly move to the next work position, point B. At point B, the label is attached to the upper side of the pack ham so that it covers the entire 3 packs. After that, move to the next step, and the label is affixed to the lower side of Packham for the entire three packs.

Since the pack ham H has a flat lower surface and an upper surface projecting in a short cylindrical shape, the overlapping surfaces are almost in line contact with each other and do not adhere to each other when they are overlapped with each other as described above. Also, since the friction coefficient with the wrapping paper and with the belt conveyor is also small, if the second belt conveyor 2 is intermittently moved or rapidly moved as it is, the overlapping portion will not be overlapped due to the inertia force of the pack ham H. Deviate from the rules.

In this case, it is possible to use a stepped belt conveyor as the second belt conveyor and hook the edge of the pack ham H on the step of the belt conveyor to prevent the shift, but the edge of the pack ham H is raised. It is difficult to obtain the effect if it is curved or curved upward. Therefore, in the present invention, the pack ham H is sucked and conveyed by increasing the frictional force between the pack ham H and the second belt conveyor 2. In order to achieve the purpose, the second belt conveyor For example, 2 is made of a foam material so that the whole belt is breathable, or is formed so as to be breathable by providing a small hole, or a plurality of belts are formed at intervals in the width direction. It may be configured as follows. In the illustrated example, a large number of small holes 3 are provided in the second belt conveyor 2 to provide air permeability. The small holes 3 are formed over the entire circumference of the endless belt at intervals for each block because the three-stage overlapping position A and the working position B are different. The small holes 3 formed in each block are provided at three positions with a distance of one-fourth of the total length of Packham H in order to shift and stack Packham H by a quarter. The size and number of the small holes 3 are determined by the weight of the pack ham H, the coefficient of friction with the belt conveyor 2 and the suction force of the vacuum chamber described later. Although not shown, a guide plate may be provided on the second belt conveyor 2 so that a predetermined edge portion of the pack hum H surely overlaps with a predetermined small hole 3 position.

Below the second belt conveyor 2, a vacuum chamber 4 is arranged with its opening facing upward as shown by a dotted line. The vacuum chamber 4 is provided so as to extend from the first small hole 3 at the three-stage stacking position A 1 to the working position B 1. The vacuum chamber 4 is connected to the vacuum source via an air controller (not shown) associated with the drive controller of the second belt conveyor 2. A blower, a vacuum pump, a vacuum generator, or the like can be used as the vacuum source, but it is preferable to use a blower capable of producing a large amount of air.

Now that the configuration has been described, the operation will be described. When the pack ham H is sent by the first belt conveyor 1, the trailing edge of the pack ham H drops while being guided by a guide plate (not shown) so as to overlap the first small hole 3 of the block. The dropped pack ham H is detected by an optical sensor or the like (not shown). The control device is actuated by the signal of the optical sensor to connect the vacuum source to the vacuum chamber 4 and to intermittently move the second belt conveyor 2 by a quarter. During this movement, the pack ham H is sucked into the vacuum chamber 4 through the small hole 3 and the frictional force with the belt conveyor 2 becomes larger than the inertial force of the pack ham H, so that the position does not shift. After the movement, the next small hole 3 appears on the vacuum chamber 4, but the second belt conveyor 2 remains in the same state until the next pack ham H is sent to save the energy for the energy saving. . When the second pack ham H is sent, the same operation as the first is repeated. Also in this case, the pack ham H is sucked by the vacuum chamber 4 at the time of movement as in the case of the first movement, so that the position does not shift. If the second pack ham H drops and the first position is displaced, the vacuum chamber 4 may be left connected to the vacuum source without turning off the vacuum source. Then, when the third is sent, the vacuum source moves rapidly from the three-stage stacking position A to the working position B while being connected to the vacuum chamber 4, and the label is not displayed by the labeling device (not shown) waiting there. It can be attached. At the same time, the above operation is repeated.
